An armour-moving type AC metal closing switch device

Abstract

The invention relates to an armour-moving type AC metal closing switch device comprising a cabinet body, insulation separator plates, a vacuum circuit breaker, a current transformer, a lightning arrester and a control circuit. The insulation separator plates are positioned in the cabinet body and separate the cabinet body into a control chamber, a mutual inductor chamber, a lightning arrester chamber, a wiring chamber and circuit breaker chambers. The number of the circuit breaker chambers is two. The lightning arrester chamber and the wiring chamber are positioned right above the circuit breaker chamber. The control chamber and the mutual inductor chamber are positioned on the top portion of the cabinet body. The vacuum circuit breaker, the current transformer, the lightning arrester and the control circuit are respectively installed in the circuit breaker chamber, the mutual inductor chamber, the lightning arrester chamber and the control chamber. The control chamber, the mutual inductor chamber, the lightning arrester chamber, the wiring chamber and the circuit breaker chambers are all separated from each other by heat radiation air channels formed by the insulation separator plates. The armour-moving type AC metal closing switch device of the invention simultaneously has two mutually independent circuit outputs. On one hand, device construction cost is greatly reduced, and anti-fault capability of the device is raised; and on the other hand, the device management convenience is also improved.

Description

technical field [0001] The invention relates to a switchgear for a power supply system, specifically an armored removable AC metal-enclosed switchgear. Background technique [0002] At present, in the construction of the power supply system, the armored removable AC metal-enclosed switchgear is widely used, but as we all know, the currently used armored removable AC metal-enclosed switchgear is only equipped with a vacuum Therefore, the current armored removable AC metal-enclosed switchgear can only provide one circuit output, but in the actual power grid structure, on the one hand, it is often necessary to build multiple circuit outputs; Therefore, in order to meet the needs of actual use, when using the current armored removable AC metal-enclosed switchgear for construction, it is often necessary to use multiple equipment, which on the one hand led to an increase in the use cost of the equipment, the area occupied by the equipment, and the construction cost; At the same ...

[0002]At present, in the construction of the power supply system, the armored removable AC metal-enclosed switchgear is widely used, but as we all know, the currently used armored The removable AC metal-enclosed switchgear is equipped with only one vacuum circuit breaker, so the current armored removable AC metal-enclosed switchgear can only provide one circuit output, but in the actual power grid structure, on the one hand, it is often It is necessary to build multiple circuit outputs. On the other hand, in order to improve the stability of the power supply line, it is often necessary to provide reliable backup redundant circuits for the control circuit. Therefore, in order to meet the needs of actual use, the current armored removable During the construction of AC metal-enclosed switchgear, it is often necessary to use multiple devices, which on the one hand leads to an increase in the use cost of the equipment, the area occupied by the equipment and the construction cost, and on the other hand also causes the workload of equipment maintenance and daily maintenance management. And labor intensity increases, which is not conducive to the stable operation of power supply lines. At the same time, the heat dissipation structure of the current armored removable AC metal-enclosed switchgear still adopts the traditional overall ventilation and heat dissipation method. On the one hand, the heat dissipation efficiency is low, and on the other hand On the one hand, it is also easy to cause dust to deposit on electrical equipment, and in severe cases, it will cause a short circuit or abnormal discharge between electrical equipment, which seriously threatens the operation safety of the power supply circuit. Therefore, it is urgent to develop a new armored mobile phone for this situation. Open AC metal-enclosed switchgear to meet the needs of actual use
