Fully Insulated ring mesh cabinetsThere are two forms: air insulation and fully enclosed inflatable cabinets. Air insulation is a system connected by a copper row through a common SF6 load switch. Fully enclosed inflatable cabinets in addition to the power into the outlet, there are special connectors, the cabinet is connected with a complete air chamber, the gas room is filled with SF6 gas.

Fully insulated ring cabinet: Also known as HXGN. Originally refers to the switch cabinet used for ring network distribution, because of its simple structure, commonly used load switch plus fuse combination. Later, as soon as you see this switch, all the batches of ring cabinets.

The fully insulated ring cabinet is a set of high voltage switchgear installed in the steel plate metal cabinet or assembled into the power supply unit of the spacer Ring network. Its core component is the high-voltage switchgear. Use load switches and fuses. It has the advantages of simple structure, small volume, low price, improved power supply parameters and performance, power supply safety and so on. It is often referred to as a load switchgear in a medium voltage system.

High pressure basically no switchgear, because the voltage is too high, so there is a switchgear, do not need to be installed in the cabinet; You said the switchgear is a medium-voltage switchgear, Medium voltage switchgear in the "simplified" version for the connection between the medium voltage line and distribution, that is, the ring cabinet, so the ring cabinet is a medium pressure cabinet;

The main body of the switchgear is a switch, which has the function of connecting and disconnecting the load current, as well as the function of cutting off the fault current. This feature is significant because when the load current is 1A, the short-circuit current may reach 1000A, making it more difficult to switch 1000A if it is easy to switch according to 1A. For different purposes, people make a switch that can turn the load current on or off. Switch cost is low, can not be combined with protection, known as "load switch." It also creates a switch that can cut off the short-circuit current. It has the characteristics of strong arc extinguishing ability, complex structure and high cost. Can be used in conjunction with protection and automation devices. It is called a "circuit breaker." Switchgear is generally equipped with arc extinguishing capacity circuit breaker, ring cabinet is equipped with arc extinguishing capacity of the circuit breaker. Load switches that can only be operated manually;

The fully insulated ring cabinet is an upgraded product of the isolation switchgear. The operating current is cut off by the contactor load switch. The short-circuit current is cut off by the fuse. Switchgear can be installed a variety of protection devices, design a variety of protection: overcurrent, Speed break, grounding, mean difference, negative sequence, inverse power, reclosing, etc., isolated switchgear only use fuse protection.

Although the time is not long, the fully insulated ring cabinet has been widely used, mainly due to the new development of industrial enterprises and institutions. The middle cabinet is mainly used for power plant, small and medium-sized generator power supply, power system two substation power supply, industrial and mining enterprises and institutions power distribution, large high-voltage motor startup, etc., according to its use and other characteristics to choose which one to use. Daily necessities that meet our work and life needs.
