Problems solved by technology

[0004] When operating the operating handle on the functional unit of the control center, if using the Figure 10 ~ Figure 14 As mentioned in detail, the way to hold the operating handle differs from individual to individual. If you use the wrong grip to operate, you may not be able to operate with the required force, or your fingers may turn blue even if you can operate.
In the case of a large-scale circuit switch operation device, the above-mentioned problems are further exacerbated because the operating load becomes larger

Abstract

An electric circuit opening and closing operation device which allows the operator to grasp the operation knob correctly with no individual variation and stably perform the opening and closing operation is provided. The operation knob (6b) is formed with a dent (6d) which allows the operator to grasp the operation knob (6b) with his thumb's side naturally fit in with the dent (6d) and easily turn the operation knob (6b) clockwise with his hands grasping the operation knob (6b) to turn the electric circuit opening and closing operation device from an OFF state to an ON state. By providing a nail slip-in preventing means between a design panel (6c) and the operation knob (6b), the slip-in of the operator's nail can be prevented.

Description

technical field [0001] The invention relates to a circuit switch operating device arranged on a functional unit of a control center. Background technique [0002] In JEM-1195 (JEM: Japan Electrical Manufacturers Association Standard), the so-called functional unit of the control center is defined as a circuit of the motor control center including the main circuit and auxiliary circuit equipment required to meet a certain function Constituent unit. A circuit breaker is usually installed in this functional unit to safely break the current in case of a short circuit. In the circuit breaker, there is provided an external circuit switch operation device with an operating handle for easy switching operation of the circuit breaker, and when the circuit breaker is in the closed (ON) state, there is a connection that cannot pull out the functional unit. lock function. [0003] Patent Document 1 discloses that in order to install an external operating handle device (circuit switch ...
