Problems solved by technology

The "five-proof" padlock scheme must be operated by a special person, and the locking and opening of the grounding switch are all controlled by humans, which may cause misoperation; and the electrical circuit locking method has limitations, which are affected by the quality of electrical contacts and components. The impact is large; the above two locking schemes cannot achieve the purpose of safe and reliable locking

Abstract

The invention provides a switch cabinet and a grounding switch interlocking device for the switch cabinet. The switch cabinet is provided with a cabinet body, a grounding switch and an operating spindle, wherein the operating spindle has a closing position and an opening position. The interlocking device of the switch cabinet comprises an interlocking member, a locking mechanism and a program lock, wherein the interlocking member has a clamping position; the interlocking member is connected with the operating spindle; the locking mechanism includes an operating member, a transmission assemblyand a locking member which are connected in sequence; the operating member drives the locking member to move through the transmission assembly so as to enable the locking member to move to the clamping position for clamping and thus lock the position of the operating spindle; and the program lock is connected with the locking mechanism when the locking member is in a clamping state with the clamping position so as to lock the position of the locking mechanism. In the technical scheme of the invention, the position of the operating spindle is locked through the mechanical transmission mechanismand the program lock, and the locking reliability is effectively improved.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a switch cabinet and a grounding switch interlocking device for the switch cabinet. Background technique [0002] At present, in the common high-voltage switchgear on the market, most of the interlocking schemes for the grounding switch use "five-proof" padlocks or electrical circuit locking (locking electromagnets) to solve ground knife locking. The "five-proof" padlock scheme must be operated by a special person, and the locking and opening of the grounding switch are all controlled by humans, which may cause misoperation; and the electrical circuit locking method has limitations, which are affected by the quality of electrical contacts and components. The impact is large; the above two locking schemes cannot well achieve the purpose of safe and reliable locking. Contents of the invention [0003] The invention provides an interlocking device for a switchgear and a grounding s...
