Abstract

The invention relates to a 10KV electric power complete equipment misoperation-preventive lock which is formed by a measuring cabinet and an electricity receiving cabinet. The 10KV electric power complete equipment misoperation-preventive lock is characterized in that a mechanical linkage lock is mounted between a measuring cabinet door and an isolating switch of the electricity receiving cabinet, an operation mechanism of the isolating switch of the electricity receiving cabinet is matched with a lower door of the measuring cabinet through the mechanical linkage lock, a microswitch is mounted on the inner side of the measuring cabinet, the power source signal of the microswitch is connected with a voltage transformer in the electricity receiving cabinet, and the microswitch is connected with a sound-light alarm device above an incoming line cabinet of the electricity receiving cabinet in an electromagnetic mode. The 10KV electric power complete equipment misoperation-preventive lock has the functions of mechanical interlocking and electromagnetic alarming, the double insurance of personal safety and misoperation prevention of a high voltage measuring device are achieved, and casualty accidents of electric shock of persons are avoided effectively.

Description

technical field [0001] The invention relates to an anti-misoperation locking of 10 kilovolt electric complete sets of equipment, which is used for 10 kilovolt electric complete sets of equipment. Background technique [0002] The on-site installation, inspection and maintenance of 10 kV high-voltage electric energy metering devices has the characteristics of small and scattered work sites, multiple points and wide areas, and the specific working time of a single site is relatively short. The electrician of the customer is responsible for operating the high-voltage equipment and implementing safety measures. There are some safety hazards in field work. The health level of user equipment varies in thousands of ways under the operating state, and the degree of emphasis on management and the quality of electricians are uneven, which makes it difficult for users to implement the "two votes" system in safety management, resulting in organizational measures to ensure the safety of ...
