Metal-clad movable-type alternate current metal-enclosed switchgear

Abstract

The invention relates to a metal-clad movable-type alternate current metal-enclosed switchgear. The metal-clad movable-type alternate current metal-enclosed switchgear comprises a base, a cabinet body, partition plates and a cooling device, wherein the bottom part of the cabinet body is mounted on the base; a plurality of partition plates are embedded inside the cabinet body; the partition plates divide the cabinet body into a low pressure chamber, a cable chamber, a busbar chamber, a circuit breaker chamber and a display control chamber which are distributed mutually independently; the cabinet body includes locating keels and protection plates; the protection plates are respectively connected with inner surfaces and outer surfaces of the locating keels; and the cooling device includes ventilator fans, a semiconductor refrigeration device, silica gel heating wires, electrostatic dust removal nets and an air filtering device. According to the metal-clad movable-type alternate current metal-enclosed switchgear, on one hand, during operation, the regulation and control capability and the adaptive capability of the metal-clad movable-type alternate current metal-enclosed switchgear to an environment temperature can be effectively improved, on the other hand, harmful gases leaked in the metal-clad movable-type alternate current metal-enclosed switchgear can be effectively recycled in time, thereby greatly improving the operation safety of the metal-clad movable-type alternate current metal-enclosed switchgear.

Description

technical field [0001] The invention relates to a switchgear, in particular to an armored removable AC metal-enclosed switchgear. Background technique [0002] Armored removable AC metal-enclosed switchgear is widely used in the current power supply of urban public facilities, industrial and mining enterprises and urban residents, and plays a vital role in the operation stability, reliability and safety of the power supply network. However, during the operation of the current armored removable AC metal-enclosed switchgear, due to environmental temperature changes and the operation of the box-type fixed AC metal-enclosed ring network switchgear, it is very easy to make the box-type fixed AC metal-enclosed switchgear Closed ring network switchgear is affected by temperature and has operational failures.

[0002] Armored removable AC metal-enclosed switchgear is widely used in the current power supply of urban public facilities, industrial and mining enterprises and urban residents, and plays a vital role in the operation stability, reliability and safety of the power supply network. However, during the operation of the current armored removable AC metal-enclosed switchgear, due to environmental temperature changes and the operation of the box-type fixed AC metal-enclosed ring network switchgear, it is very easy to make the box-type fixed AC metal-enclosed switchgear Closed ring network switchgear is affected by temperature and has operational failures. At the same time, sulfur hexafluoride circuit breakers are often used in current armored removable AC metal-enclosed switchgears. Although this circuit breaker has good operating performance, it is in During operation, especially when a fault occurs, it is very easy to cause highly polluting sulfur hexafluoride gas to leak, thereby causing serious damage to the surrounding environment, equipment and staff. To address these problems, the current main treatment methods are Armored removable AC metal-enclosed switchgear is equipped with a ventilation fan on the top of the cabinet to cool down and dilute harmful gases. On the one hand, this method has low cooling efficiency and is likely to cause the spread of harmful gas pollution. Therefore, the use effect is relatively poor. At the same time, when the ventilation fan is currently used for cooling operations, it is very easy to cause polluting dust, liquid droplets and conductive particles in the external environment to enter the interior of the armored removable AC metal-enclosed switchgear, and damage the armored removable AC metal-enclosed switchgear. Metal-enclosed switchgear causes pollution, thereby increasing the failure rate of armored removable AC metal-enclosed switchgear, so in view of this phenomenon, it is urgent to develop an inventive armored removable AC metal-enclosed switchgear to meet practical needs
