(Summary description)The high-voltage connector is suitable for connecting 1140V～10kV power cable circuits in the tunnels of coal mining and tunneling in underground coal mines. It can be used for wiring of UGSP monitoring shielded various rubber-sheathed cables in mobile substations for power supply. They can be connected at both ends of the cable for mutual plugging, or half of the explosion-proof connection part can be connected to the mobile substation. The following describes the maintenance and maintenance of high-voltage connectors.
1. During the use and maintenance of high-voltage connectors, prevent the explosion-proof surface from colliding or rusting.
2. During the maintenance process, the high-voltage connector is strictly prohibited from live operation. After the power is cut off, it must be ensured that there is no residual voltage before unplugging and disassembling any part. The residual charge can be discharged by reliable means in accordance with coal safety regulations, and mobile power stations can also be used The operation sequence of decay discharge is as follows:
2.1. Generally, the load switch is kept closed before operation, the high-voltage switch is opened and the "no switch-on" sign is added or locked, and then the connector is operated. If there is feedback from low voltage, the feed switch and load switch should be opened first .
2.2. If the load switch is disconnected when the high-voltage connector is pulled, mark or lock the high-voltage switch before opening the high-voltage switch, and then close the load switch for at least one minute to discharge the residual voltage to ensure safety, and then perform the necessary operations .
2.3. When reinstalling the high voltage connector, it must be fully plugged in before powering on.
2.4. After the flange of the middle shell of the high-voltage connector is unplugged, if it needs to be kept for a period of time, it should be covered with a cover and still sealed with a sealing gasket to prevent moisture intrusion.
Shanghai Huzheng Electronic Technology Co., Ltd. is committed to providing integrated solutions for energy storage connectors, industrial connectors, new energy vehicle connectors, wind power connectors, industrial connectors, high voltage connectors, and photovoltaic energy storage connectors. Product design and application experts. The company's products can be widely used in fields such as new energy vehicles, heavy machinery, trains and railway tracks, solar energy, wind energy, smart grids and machines.

Types and styles of good price and quality Waterproof connector Manufacturers china
Many factors determine the types and styles of good price and quality Waterproof connector Manufacturers china, among which the frequency and service scale of the mating cable are the most important factors. In practical engineering, in order to reduce the reflection to a large extent, the small diameter is as close as possible to the diameter of the cable. The greater the difference between cable diameter and arc welding diameter, the worse the performance. The function of inverse ratio is added. Generally, the performance of small Waterproof connector Manufacturers china is very good in the high frequency band. When the frequency is very high (above 26ghz), it is a dielectric waterproof connector. - Wholesale New energy vehicle connector on sales must have three characteristics 2022-06-21
