Abstract

The invention discloses a valve locking device for an armored withdrawable switch cabinet. A movable plate, a baffle and a limiting plate are horizontally placed in sequence from top to bottom. A longitudinal slotted hole I is formed in the rear protruding part of the right end of the movable plate. The limiting plate is fixed to a cabinet body, and a transverse slotted hole II is formed in the middle of the limiting plate. A round hole is formed in the middle of the baffle. A bolt I penetrates through the slotted hole I, the slotted hole II and the round hole in sequence from top to bottom. A bolt II penetrates through the front right end of the movable plate and the front right end of the limiting plate in sequence from top to bottom, so that the movable plate and the limiting plate are hinged. The rear end of a spring is fixed to the rear left end of the limiting plate, and the front end of the spring is fixed to the rear end of the rear protruding part of the movable plate. The valve locking device has the advantages of being flexible, convenient to use, safe, reliable and easy to install.

Description

technical field [0001] The invention relates to a valve locking device of a switch cabinet. Background technique [0002] At present, with the extensive application of KYN28A-12(Z) series armored removable high-voltage switchgear in 10kV power distribution system, the safety of its operation and maintenance has been paid more and more attention by users. Wherein, it is more and more important to prevent the measures of opening the cabinet valve by mistake. [0003] The original cabinet design mainly considered the safety of equipment and personnel from the protection level of the cabinet shape. But in actual work, you will encounter the situation of live maintenance of the circuit breaker room. In the state of maintenance, the valve may be accidentally opened by tools or personnel. Once the valve is opened, it is very easy to cause an electric shock accident. Contents of the invention [0004] In order to solve the above-mentioned purpose existing in the prior art, the...
