AC withstand voltage test Transformer eight characteristics AC withstand voltage test transformer core is a single-phase core type, using high-quality cold-rolled oriented silicon steel laminated, fastening method using steel as a clip. The high-voltage coil is a cylindrical multilayer tower, which is made of high-quality polyester enameled wire and high-voltage insulation material. AC withstand voltage test Transformer low voltage coil outside, the instrument coil is a separate winding, under normal circumstances is 100V. The housing is octagonal and the test transformer above 10KVA is equipped with a movable iron wheel. With the advantages of light weight, small size, easy movement, superior performance and other special AC withstand voltage test transformer's main technical indicators> Rated capacity: 1 ~ 300KVA

AC voltage withstand test transformer Note 1, to do high-pressure test, must be 2 or more than 2 people to participate, and clear division of labor, clear contact between each other. There are special people to monitor the safety of the site and observe the test status of the test sample;
2. The transformer and control box should have reliable grounding;
3. During the test, the boosting speed must not be too fast, and sudden full-voltage power-on or power-off must not be allowed.
4. In the process of step-up or withstanding voltage test, if any of the following abnormalities are found, it should be immediately depressurized, and cut off the power supply, stop the test, and check the cause of the AC voltage withstand test transformer before doing the test. 1 The voltage meter pointer swings a lot; 2 The smell of burning insulation and smoke are found; 3 There is abnormal sound in the tested product.
5. During the test, if the sample is short-circuited or breakdown, the over-current relay in the control box will work. At this time, the regulator will be returned to zero and the sample can be taken out after the power is cut off.
6. When conducting capacitance test or DC high-pressure leakage test, after the test is completed, lower the voltage regulator to zero and cut off the power. Then, discharge the high-voltage terminal of the test sample or capacitor to the ground with the discharge rod to avoid The potential remaining in the capacitor is at risk of electric shock.

M Type Pallet Wrapping Machine
Many customers have limited space to use machines, and it is not convenient to load and unload by forklifts. We have customized M type pallet wrapping machine for this part of customers. With the increase in market usage, Dahong Intelligent has standardized the production of this M type machine. The M type of the pallet wrapping machine has a hole for loading and unloading goods with manual forklifts. The advantage of this M-hole position is that it does not require customers to build the foundation separately (for example, the equipment is inconvenient for the foundation on the second floor), and does not need to be equipped with a ramp board (the space is small and can not fit).
