China Independent R & D High Speed ​​Rail Permanent Magnet Traction Motor Breaks International Technology Monopoly

CSR CSR Zhuzhou Electric Co., Ltd. disclosed on the 22nd, the company jointly developed with the national key university Zhejiang University, included in the national 863 plan "key high-speed railway key technology and equipment development project," with completely independent intellectual property rights of TQ -600-type permanent magnet synchronous traction motor, in the company's state-level testing pilot station successfully passed the test validation, has a good "anti-demagnetization" capability, the performance indicators meet the design requirements, becoming the first country through the national Verified High Speed ​​Rail Permanent Magnet Traction Motor.

It is understood that this type of permanent magnet synchronous traction motor will be the first to be equipped with a large number of 350km / h high-speed rail already in service in early 2014 to further enhance the competitive advantages of China's high-speed railway in terms of energy saving, emission reduction, safety and comfort, marking the breaking of China's high-speed railway International technology monopoly success into the era of permanent magnet drive.

He Yunfeng, director of the company introduced the introduction of permanent magnet traction motor with a large power density, high power conversion efficiency, overload protection and other advantages, while the permanent magnet loss of magnetism is plagued its popularization and application of worldwide problems. TQ-600-type permanent magnet synchronous traction motor using the world's new rare earth permanent magnet materials, the coercive force up to 381h, magnet stability, anti-demagnetization ability. When the test temperature reaches 180 ℃, the irreversible loss of permanent magnet is less than 5%. Through the finite element simulation analysis, the permanent magnet completely meets the demagnetization requirements of the motor. In a variety of operating conditions, the permanent magnet will not demagnetization, to ensure the reliability of motor performance.

It is understood that a group of eight high-speed rail group with TQ-600 permanent magnet motor driven, relative to the current 365 kW AC motor, a single motor power increased 65% to 600KW, the maximum power of 635kW, the total number of motors can be reduced by 24 For 13 units. The power density of a single motor is increased by 31.5% and the weight is reduced by 1/3. The total weight of a train motor is reduced by 3165kg, equivalent to the weight of more than 50 adults and reaching the international advanced level. This is of great significance to further saving energy and reducing consumption of China's high speed railways.

According to reports, the motor in the insulation performance, ventilation structure is also a leading position in the world. Its insulation technology combines the advantages of high-power locomotive and high-speed rail traction motor insulation structure, with higher insulation reliability; using a new enclosed ventilation design to ensure that the internal cooling system clean.

Technical Data:

Application Scope:
•The product has excellent waterproof and insulating properties and is an excellent choice for the power industry and the communication industry.
•The product is suitable for cable insulation, busbar insulation, communication base station insulation, transformer insulation, etc.
•Wrap the wire with this product as a partial insulation treatment.
•Waterproof sealing and insulation protection for overhead line clamps.
•Waterproof sealing and insulation protection of exposed metal parts of electrical connection.
•Repair of damaged cable terminals.
•Insulation and sealing of exposed metal parts of the busbar connections for the switchgear.

Application Demonstration 1: 10KV overhead bare conductor insulation treatment

The overhead bare wires are too close to the building, and the safety distance is not enough. For safety reason, SINOFUJI Mastic Tape is wrapped around the overhead bare wires where is near the building to play the role of insulating protection.

•Application Demonstration 2: Insulation sealing of the exposed part for the electrical connection
•Overhead insulated wire is connected to outdoor electric pole or transformer through jumper, and the connection points are exposed in the air, which is similar to wire clamp. It is easy to cause hidden safety hazard after water vapor is entered.
•The shape of these positions is generally irregular. FUJI Mastic Tape Pad can be well attached to these irregularly shaped metal connection points, and the waterproofness is guaranteed.
•SINOFUJI Mastic Tape Pad has excellent anti-ultraviolet aging performance, that can be used in outdoor environment for a long time, and has certain mechanical protection properties after being cured.

•Application Demonstration 3: Insulation and sealing protection of overhead wire clamp
•Due to its special structure and location, it is easier for clamp to be entered with water vapor and the water vapor is aggregated inside the wire clamp, thereby causing great harm.
•There are many types of overhead wire clamps, such as tension clamp, wedge clamp, parallel groove clamp, H-type clamp, etc. The general shape of the clamp is not very regular, but the SINOFUJI Mastic Tape Pad is very soft and has good adhesion to metal, so it can be applied to these irregularly shaped wire clamp position.
•SINOFUJI Mastic Tape Pad has excellent anti-ultraviolet aging performance, that can be used in outdoor environment for a long time, and has certain mechanical protection properties after being cured.

Application Demonstration 4: Insulation for Top Part of Post Insulator
•The bare conductors on both sides of the post insulator on the straight tower of the 10KV overhead line are susceptible to contact by birds or objects such as metal wires carried by birds and cause the line to trip.
•SINOFUJI Mastic Tape Pad is mainly used for insulation protection within a certain range on both sides of the post insulator to prevent short circuit.

Application Demonstration 5: Blocking the cable entry holes at the bottom of the switch cabinet and distribution box
•Generally speaking, It is difficult to block the cable inlet and outlet of the distribution box If the plugging mud is used for a long time, it will dry out. Moisture or small animals will be coming into the distribution box, and in most cases there are many cables in one inlet or outlet. insufficient adhesion will possibly cause the plugging mud fall off.
•With SINOFUJI Mastic Pad for sealing, the plasticity is better, regardless of what shape the cable is, it can be closely adhered, even to metal, it also can be used for a long time.

Application Demonstration 6: Insulation repairing of wire

•SINOFUJI Mastic Tape Pad is mainly used for insulation restoration of wire.

Application Demonstration 7: Insulation sealing of exposed metal parts in switchgear

•It is possible for moisture entering the cabinet internal body, which may cause the primary or secondary equipment to get wet, thus to cause corrosion, poor contact, short circuit and other problems that affect the insulation performance of the cabinet.

•If the exposed metal parts are Wrapped with SINOFUJI Mastic Tape Pad, so that it will not directly be contacted with the air and the degree of corrosion can be reduced.

•If overhaul is needed, then just remove SINOFUJI Mastic Tape Pad, after overhaul, rewrap the SINOFUJI Mastic tape pad, corrosion of copper bars and epoxy parts can be significantly reduced with this easy reuse process.

Application Demonstration 8: Repair of damage for cable terminal

•The crack on the top of the cable terminal can be repaired with SINOFUJI Mastic Tape Pad to delay the cracking speed, and at the same time prevent rainwater from entering the crack, thereby to prolong the life time of the terminal.

For outdoor occasion, the weather conditions should be good without rain etc. The corresponding safety measures and labor protection preparation shall be made.


•Surface Treatment:

It is recommended to use a suitable method to remove the surface oil, grease and dust first, and keep the metal surface clean and dry. If there are burrs on the surface, it is recommended to use manual or electric tool to smooth the surface.



•Working Procedure of Applying Overhead Line:

Open the vacuum packaging;

Strip off the plastic film on one side of SINOFUJI Mastic Tape Pad, and use the no plastic film side to face the overhead line and wrap it;

Strip off the plastic film gradually on another side of SINOFUJI Mastic Tape Pad, and wrap the SINOFUJI Mastic Tape Pad on the overhead wire step by step;

Continue to Wrap the overhead line with SINOFUJI Mastic Tape Pad; do not remove the film completely before to make sure SINOFUJI Mastic Tape Pad is tightly fixed with the wire;
