GKG / GKD MV LV Mine Switchgear
Description:
GKG general mine high-voltage switchgear, mainly used in places where there is no danger of gas and coal dust explosion in coal mines, such as the power supply of the central control room, car yard, general ventilation duct and main ventilation duct power distribution chamber In the system, it is used for distribution protection and control of electrical equipment with AC 50Hz voltage 3.6kv, 7.2kv or 12kv. It can also be used to directly start or start downhole fans and water pump high-voltage motors through dry reactors. This switchgear is also suitable for ground substations and power supply systems that require high protection levels such as metallurgy and chemical engineering.
| 1. GKG-1250/10(6) general mine high-voltage switchgear (hereinafter referred to as switchgear) is a self-developed product on the basis of absorbing existing advanced product technology. It has the characteristics of novel structure, convenient operation and maintenance, small size, light weight, safety and reliability; |
| 2. Structural features: The cabinet is composed of a cabinet body and a handcart. It is divided into a handcart room, a busbar room, a cable room, and a relay room by partitions. The handcart has two positions for testing and working. The handcart room and the cable room are separated by a movable insulating board, which is particularly convenient and safe during maintenance. Reduce maintenance time and improve power supply quality. The handcart slide is accurate and flexible to ensure that the handcart does not deviate in and out; |
| 3. This switchgear has a high protection level, and the enclosure protection level is Ip54, which is suitable for harsh environments. |
| 4. With advanced and complete protection: the protection function of the switchgear, after years of use in coal mines, the product can meet the protection options for different purposes, equipped with leakage, insulation monitoring, undervoltage, short circuit, overcurrent operation and overvoltage, and remote control can also be selected , Remote communication, remote sensing and other comprehensive automatic protection devices, which can be equipped with small current grounding protection line selection devices for supporting use; |
| The secondary protection function is advanced, complete and flexible. According to different loads, it can be configured with short-circuit, over-current, leakage, grid insulation monitoring, under-voltage and operating over-voltage protection. The microcomputer integrated automatic protection device with remote (remote measurement, remote signaling, remote control, remote adjustment) function is sent to the higher-level monitoring or dispatching system in time through the communication network to realize the automatic detection of power grid operation |
