10KV high voltage electric energy measuring cabinet mis-opening prevention locking device

Abstract

The invention relates to a 10KV high voltage electric energy measuring cabinet mis-opening prevention locking device which is formed by a measuring cabinet and an electricity receiving cabinet. The 10KV high voltage electric energy measuring cabinet mis-opening prevention locking device is characterized in that a locking mechanism is mounted between a measuring cabinet door and an isolating switch of the electricity receiving cabinet, the locking mechanism is formed by a locking plate, a locking rod, a shaft stationary sleeve, a crank arm, a connecting rod, a transmission rod, a pressing plate, a rotary disc and an operating handle, the locking plate is fixed on the measuring cabinet door, one end of the locking rod is matched with the locking plate, the other end of the locking rod is in movable connection with one end of the crank arm, the center of the crank arm is connected with the shaft stationary sleeve, the shaft stationary sleeve is connected with the electricity receiving cabinet, the other end of the crank arm is connected with the connecting rod and moves up and down, the connecting rod is connected with the pressing plate through the transmission rod, the upper portion of the pressing plate forms a 30-degree angle, the operating handle can be inserted into the rotary disc, and the rotary disc is matched with the upper portion of the pressing plate. The 10KV high voltage electric energy measuring cabinet mis-opening prevention locking device has a mechanical interlocking function, 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 a 10-kilovolt high-voltage electric energy metering cabinet anti-mis-opening locking device, which is used for 10-kilovolt electric power 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 ens...

AI Technical Summary

Problems solved by technology

In the part of the electric energy metering device, there is no anti-misoperation locking device between the high-voltage metering cabinet and the load switch of the incoming line, which leads to an increase in the probability of people accidentally entering the electrified interval, accidentally touching or accidentally touching the electrified equipment, and easily causing personal electric shock casualties ACCIDENT
