Abstract
The utility model relates to a component structure of a switch cabinet, in particular, relates to a switch cabinet grounding switch and lower door interlocking mechanism. The interlocking mechanism comprises a cabinet body. A the middle portion of the cabinet body is provided with a grounding switch; a lower portion of the cabinet body is provided with a fuse room; an front end of the fuse room is provided with a lower door; a front end of an operating shaft of the grounding switch is a shaft head which can be in insertion matching with an operating handle; the shaft head is connected with an interlocking disc which can rotate with the shaft head; the edge of the interlocking disc is hinged to a connecting rod; a lower end of the connecting rod is hinged with a lock pin; and the rotation of the interlocking disc enables the lock pin to move vertically on a guide seat through the driving of the connecting rod; and when the lower door is in a closed state, the lock pin move upwards and downwards to as to retreat from or insert into a lock hole on a top frame of the lower door. The switch cabinet grounding switch and lower door interlocking mechanism of the utility model has the advantages of simple structure, fewer transmission links, convenient installation and debugging, as well as high-reliability action.
Description
Technical field
The utility model relates to a kind of modular construction of switch cubicle, specifically a kind of switch cabinet grounding switch and lower door interlocking mechanism.
Background technology
Usually be provided with the fuse chamber of being sealed by the Xiamen in the cabinet bottom of regular tap cabinet, be used for installing the protection components such as fuse.When the indoor element of fuse was overhauled, the earthed switch that needs on the one hand to be installed in the cabinet middle part was operated to earthing position, to guarantee the fail safe of maintenance process, does not allow to open the Xiamen when namely earthed switch is not in earthing position and overhauls; Finish and do not allow earthed switch is operated when closing the Xiamen in maintenance not on the other hand, to ensure maintainer's safety.The interlocking device that above-mentioned safety regulations need to arrange earthed switch and Xiamen usually guarantees that existing interlocking device exists the defectives such as complex structure, operation is inconvenient, Interlock Reliability is poor mostly, can't satisfy higher safety operation requirement.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure, easy to operate, interlock reliable switch cabinet grounding switch and lower door interlocking mechanism are provided.
Switch cabinet grounding switch of the present utility model and lower door interlocking mechanism include the cabinet of switch cubicle, and the cabinet middle part is equipped with earthed switch, and the cabinet bottom is provided with the fuse chamber, and fuse chamber front end arranges the Xiamen; The operating axis level of described earthed switch vertically arranges, and the front end of operating axis is the spindle nose that can cooperate with the operating grip grafting; Described spindle nose is positioned at the frame top, top of Xiamen, and being connected with one on the spindle nose can be with the inter-locking panel of spindle nose rotation, and the inter-locking panel edge is hinged with a connecting rod, and connecting rod lower end and a lock pin are hinged; Described lock pin vertically is inserted in the pilot hole on the guide holder, and it is vertically mobile on guide holder that the rotation of inter-locking panel can drive lock pin by connecting rod; When the earthed switch operating axis turns to ground connection or isolated location, be with respectively pendulum lock pin to move up or down; When the Xiamen is in closed condition, lock pin move up and down the lockhole that can extract out or insert on the lower head jamb.
Spindle nose the place ahead of described operating axis is provided with an interlock plate, and the interlock plate middle part is hinged on the cabinet and can swings, and interlock plate top can stop or open the handle insertion position in spindle nose dead ahead in swing process; Be provided with spring between described interlock plate and the cabinet, spring force is rocked to interlock plate to stop the position in spindle nose dead ahead when open the Xiamen; Described lower head jamb inboard is provided with a guiding incline, and described guiding incline can drive the interlock plate hypomere when the Xiamen is closed, and interlock plate is rocked to open the position in spindle nose dead ahead.
The utility model is simple in structure, transmission link is few, installment and debugging is convenient, Reliability of Microprocessor is high.
