Embodiment Construction

[0010] like Figure 1~2 The dust-proof door of a high-voltage capacitor cabinet shown includes a cabinet door 1, and a pair of parallel channels 2 are arranged on the inner side of the cabinet door 1, and a dust-proof net 3 is embedded in the channel 2. The cabinet door 1 is evenly provided with a number of vents 4; when the cabinet door 1 is in the open state, the dust-proof net 3 can be pulled out of the channel 2 to realize separation from the cabinet door 1; the end of the dust-proof net 3 is provided with a protrusion 4. There is a groove on the inner side of the channel corresponding to the protrusion, and the protrusion can be snapped into the groove; the channel is fixed on the inner side of the cabinet door by bolts or glue.

Abstract

The invention discloses a dustproof door of a high voltage capacitor cabinet. The dustproof door comprises a cabinet door. A pair of parallel channels opposite to each other is arranged on the inner side of the cabinet door. A dust screen is inserted into the channels. The cabinet door is evenly equipped with a plurality of ventilation ports. When the cabinet door is open, the dust screen can be pulled out of the channels to separate from the cabinet door. Compared with the traditional technology, the dustproof door of the invention ensures the dustproof effect by tightly combining the dust screen with the channels, and at the same time, ensures the continuous heat dissipation through the corresponding of the dust screen to the ventilation ports.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a dust-proof door of a high-voltage capacitor cabinet. Background technique [0002] The capacitor cabinet replaces the original civil power distribution room and distribution station, and becomes a new type of complete power transformation and distribution device, which is widely used in people's lives. In traditional technology, half of the capacitor cabinet is equipped with components such as circuit breakers, thermal insulation switches, thermal relays, contactors, lightning arresters, capacitors and reactors. These components will generate more heat during operation, especially reactors. It is the main heating element, and it can reach above 70°C during operation. Usually, people will be provided with hollowed-out windows on the cabinet body accordingly, so as to dissipate the heat in the cabinet body. However, when considering the heat dissipation inside the ...
