Abstract

The invention belongs to the technical field of high-voltage switch equipment, and particularly relates to a combined electric appliance. The combined electric appliance comprises a combined electric appliance body and a control cubicle, and the combined electric appliance body comprises a circuit breaker, a two-station isolating switch, a grounding switch, a three-station isolating and grounding combined switch and operating mechanisms of the circuit breaker, the two-station isolating switch, the grounding switch and the three-station isolating and grounding combined switch; and a control loop is arranged in the control cubicle and comprises a circuit breaker opening / closing loop, an isolating switch control loop, a grounding switch control loop and a three-station isolating and grounding combination switch control loop, and relays in the loops are onboard relays. The combined electric appliance body adopts the three-position isolation grounding combined switch, so that the product structure is more compact; and moreover, the relays of various loops in the control cubicle adopt onboard relays, so that the use of the traditional relays of the control loops and the workload of secondary wiring are greatly reduced, and the space of the control cubicle is saved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and in particular relates to a combination electric appliance. Background technique [0002] GIS (GAS insulated SWITCHGEAR) combined electrical equipment, also known as gas insulated fully enclosed combined electrical equipment, is an important electrical equipment commonly used in substations. Combined electrical appliances include circuit breakers, isolating switches, grounding switches, transformers, busbars, connectors and outlet terminals, etc. The safe and stable operation of switchgear in combined electrical appliances is directly related to the safety and reliable power supply of the power grid. [0003] At present, through one-button sequential control transformation, robot inspection, live detection and online monitoring new technology application, etc., the state perception ability of switchgear has been greatly improved. However, at present, the primary body of GIS co...
