Abstract
The invention discloses a locking device for a ground switch of an electrical switch cabinet, which comprises a lock base and a lock latch. The lock base comprises a lock base body and a holding hole formed in the lock base body, the lock base body is fixedly arranged on the body of the switch cabinet, and a ground switch operating block is positioned within the holding hole. The lock latch comprises a lock latch body, which is hinged to the lock base body and covers the holding hole. The ground switch operating block can be accommodated in the space between the upper edge of the lock latch body and the holding hole and in the space between the lower edge of the lock latch body and the holding hole. Two locking lugs are arranged between the lock latch body and the lock base body respectively and engaged with each other, and hanging holes are formed in the locking lugs. The locking device can effectively ensure that the ground switch is set in an opening or closing position to prevent forced destructive operation or error operation applied by operators.
Description
Technical field
The present invention relates to a kind of earthed switch locking system, refer to especially a kind of electric switch cabinet earthing switch lock locking apparatus.
Background technology
Cabinet is corollary equipment in the controller switching equipment, when switch cubicle contains earthed switch, the pass opens the door-and a deciliter earthed switch-propelling shifts out the correlation step such as circuit breaker cart-close minute circuit breaker and must just can finish associative operation with correct operation sequence and step, and five anti-interlocking devices on the switch cubicle can prevent that abnormal operation or misoperation from can not carry out certainly.By normal operation sequence, the operation electrician can carry out the per pass program more easily, five anti-interlock parts can allow wrong operation not carry out, the rough power of operation electrician forced use that yet indivedual nothing cards is still arranged or do not train has been destroyed five anti-interlockings, and may further do down one risky operation, thereby advance handcart when causing service position splice grafting ground switch or earthed switch co-bit, and therefore cause the heavy losses of life and property.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric switch cabinet earthing switch lock locking apparatus is provided, and this locking system can guarantee effectively that earthed switch is in unlatching or off-position, avoids the enforceable destructive procedure of operator and misoperation.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of electric switch cabinet earthing switch lock locking apparatus, comprise lock and snap close, this lock comprises the lock body, the lock body is provided with putting hole, the lock body is fixedly installed on the cabinet of switch cubicle and the earthed switch operating block is positioned at putting hole, described snap close comprises the snap close body, the snap close body is articulated on the lock body and the described putting hole of buckle closure, between the upper edge and putting hole of described snap close body, all can hold the earthed switch operating block between the lower edge of snap close body and the putting hole, be respectively equipped with the lock ear that cooperatively interacts between described snap close body and the lock body, the lock ear is provided with the hook hole that padlock is installed.
As a kind of preferred scheme, be connected for bolt between described lock body and the switch cubicle.
As a kind of preferred scheme, be welding between described lock body and the switch cubicle.
As a kind of preferred scheme, described snap close body is provided with a pair of hinged block, corresponding, described snap close body is provided with a pair of hinged ear corresponding with hinged block, and jointed shaft is hinged between this hinged block and the hinged ear.
After having adopted technique scheme; effect of the present invention is: owing to utilize the snap close and the lock that cooperatively interact to protect; utilize between the lower limb of space between the top edge of snap close and the putting hole or snap close and the putting hole space can mandatoryly force operating block to be in and open or off-position, and can utilize padlock locking.Can guarantee effectively that like this earthed switch is in unlatching or off-position, avoids the enforceable destructive procedure of operator and misoperation.
