Abstract
The invention discloses an electric lock for an operation circuit, comprising: a housing, a moving contact group, a static contact group, an elastic assembly, a button, and a lock cylinder assembly; the button includes a button cap and a pressing rod, and the The lock cylinder assembly includes a lock cylinder and a lock cylinder connecting rod. The lock cylinder connecting rod is arranged at the bottom of the lock cylinder and is rotatably arranged in the housing together with the lock cylinder. The lock cylinder connecting rod is controlled by the lock cylinder. The lock cylinder is driven, and the pressure rod can be controlled by the rotation of the lock cylinder connecting rod, so that the pressure rod is in a locked state or an unlocked state. The present invention avoids the problem that the operation circuit needs to be turned on twice by integrating the lock cylinder with the mechanical switch, and also reduces the number of components and the cost of use of the equipment, and also reduces the risk of operation failure; It is hidden inside the electric lock, and the mechanical switch directly or indirectly controls the conduction of the conduction part, which avoids the possibility of vicious operation caused by artificial short-circuiting of wires.
Description
technical field [0001] The invention relates to the technical field of substation error prevention, in particular to an electrical lock used for an operation circuit. Background technique [0002] as attached figure 1 As shown in the circuit diagram of , the prior art switch knife switch error prevention system generally connects both an electric lock and an ordinary operation button or a switch in series in the operation circuit to realize the on and off of the operation circuit. The usual operation process is that when opening and closing operations are required, first turn on the electrodes at both ends of the electrical lock through the computer key, and then press the operation button or turn the transfer switch to turn on the operating circuit to realize the opening and closing operation of the switch knife switch. [0003] Problems existing in the prior art: On the one hand, the exposed electrodes of the electrical lock cannot avoid the vicious operation behavior of ...
