Control cabinet for outdoor high-voltage switch equipment

Abstract

The invention discloses a control cabinet for outdoor high-voltage switch equipment. The control cabinet for the outdoor high-voltage switch equipment solves the problems that due to the facts that three-position switching operation mechanisms are arranged outside an existing control cabinet for the outdoor high-voltage equipment and dispersed, and a water shield and a heater need to be installed on each three-position switching operation mechanism independently, cost is high and maintenance is not convenient. The control cabinet for the outdoor high-voltage switch equipment is characterized in that a cabinet body is provided with three cabinet chambers, one or two three-position switching operation mechanisms are installed in the left cabinet chamber, and one three-position switching operation mechanism and two density relays are installed in the right cabinet chamber. The control cabinet for the outdoor high-voltage switch equipment has the advantages that due to the fact that the two or three three-position switching operation mechanisms are moved into the cabinet body from outside, water resistance, dust prevention and damp resistance are benefited. The control cabinet for the outdoor high-voltage switch equipment further has the advantages that the phenomenon that each three-position switching operation mechanism needs to be provided with the heater independently is avoided, and therefore cost is reduced. In addition, the control cabinet for the outdoor high-voltage switch equipment has the advantages that due to the fact that the three cabinet chambers are arranged independently and do not disturb each other, an observation window is installed in each cabinet chamber, the working states of the three-position switching operation mechanisms arranged in the cabinet chambers can be conveniently observed, and maintenance and overhaul can be convenient.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrical appliances, in particular to a control cabinet for outdoor high-voltage switchgear. Background technique [0002] The control cabinet is an important control element on the switchgear and plays a very important role in the entire power transmission and distribution system. The existing control cabinets for outdoor high-voltage switchgear are only equipped with secondary side electrical components, control buttons, density relays and wire slots, and there is no three-position switch operating mechanism, but the three-position switch operating mechanism is placed in the control Outside the cabinet, it is scattered according to the shape of the outdoor high-voltage switchgear. Because it is an outdoor product, each three-position switch operating mechanism needs to be separately installed with a waterproof cover and heater, which is costly and not conducive to maintenance.

Problems solved by technology

The existing control cabinets for outdoor high-voltage switchgear are only equipped with secondary side electrical components, control buttons, density relays and wire slots, and there is no three-position switch operating mechanism, but the three-position switch operating mechanism is placed in the control Outside the cabinet, it is scattered according to the shape of the outdoor high-voltage switchgear. Since it is an outdoor product, each three-position switch operating mechanism needs to be separately installed with a waterproof cover and heater, which is costly and not conducive to maintenance.
