Product Description
(one)Application
PJG630/6Y Mine-used Flameproof and I.S. High- voltage Vacuum Power Distribution Device with Permanent Magnetism is suitable for underground coal mines with explosive gases such as methane. It can control, protect and measure 3-phase neutral-point ungrounded power supply systems which are at rated voltage 10KV/6KVrated current up to 630 A.
(two)Features
Besides all the feature and advantages of spring energy storage tgpe it also has its unique advantages, such as simple structure and operation, high reliability, maintenance free and long-life endurance.
1.A kind of new actuating mechanism of electromagnetic operation, permanent magnet hold and electronic control is used^ it greatly improves the stability and reliability of this product because the new mechanism employs permanent magnets for terminal position holding instead of tripping/locking devices and this obviously reduces components and prevents abrasion The integrated bistable state design requires simple structure with less actuating components and less noise, and ensures the device with long-life endurance and free from maintenance.
2.The horizontal fast-open structure makes it easier to openand close.
3.With exclusive protection for underground coal mines, ithas protection functions such as overload, short-circuit directional power leakage, insulation fault, over or under voltage air, electricity and methane interlocking. Its strong anti -interference ability adapts it to the hazardous environments in coal mines. With an LCD display drop-down menu it gives detailed real-time information about the "working environment and the humanized interface is convenient for operation and routine inspection
4.Four types of structure a, b,c, d are available so as tomeet different demands of current-carrying, communication, feedback, or direct control.
5.The switch can be switched on or off automatically or manually.
6.The remote control signal is intrinsically safe.
7.With the communication interface it enables networking with the communication station and remote monitoring function.
