Abstract
The utility model discloses an interlocking device between a fuse combination electrical cabinet and a box transformer substation screen door, which comprises a mechanism panel, a support, a lock body, a baffle and a mechanism operation shaft and is characterized by also comprising an elastic cylindrical pin. The support is fixed on the mechanism panel through a bolt, the lock body is fixed on thesupport through a screw, the lower part of the lock body is a lock tongue, the baffle is installed on the lock tongue through a screw, the mechanism operation shaft penetrates through the mechanism panel, a round hole is arranged at one end of the mechanism operation shaft near the baffle, and the elastic cylindrical pin is fixed in the round hole. The utility model can reliably ensure interlocking between a load switch-fuse combination electrical cabinet and the box transformer substation screen door by adopting the interlocking device and enhance the safety of operation.
Description
Technical field
The utility model relates to a kind of interlock, particularly relates to a kind of fuse combined electric apparatus cabinet and case and becomes the interlock of netting between the door.
Background technology
It is to finish that the special use of cable line is electrically connected equipment in the distribution system that outdoor case becomes, and is used for the open air, provides convenience for the cable of distribution system connects.Outdoor case becomes to be made up of hyperbaric chamber, transformer room and low-pressure chamber; usually adopt the switch-fuse combination cabinet to protect transformer; on-load switch is a kind of device for switching of deciliter normal load electric current impotentia deciliter short circuit current of having the ability; fuse is a kind of overcurrent relaying protection and cut-offs the equipment that cut-offs that element is integrated; normal and the fuse adapted of on-load switch is born the task of short circuit interruption by fuse.Under normal operation, have only when switch-fuse combination cabinet ground connection, the net door of transformer room can be opened.But existing switch-fuse combination cabinet and case become the reliable interlock of shortage between the net door, might be when the combined electrical apparatus cabinet to be unearthed, and the operator opens transformer room's net door, causes security incident.
Summary of the invention
At the problems referred to above, main purpose of the present utility model is to provide a kind of switch-fuse combination cabinet and case to become the interlock of netting between the door, the utility model solves above-mentioned technical problem by following technical proposals: the utility model comprises mechanism's panel, support, lock body, baffle plate, mechanism's operating axis, it is characterized in that: described interlock also comprises elastic cylindrical pin, described support is by being bolted on the described mechanism panel, described lock body by screw on described support, the lower part of described lock body is a dead bolt, described baffle plate is installed on the described dead bolt with screw, described mechanism operating axis passes described mechanism panel, end near baffle plate on the described mechanism operating axis is provided with circular hole, and described elastic cylindrical pin is fixed in this circular hole.
Wherein, when described elastic cylindrical pin turned to vertical position, one of elastic cylindrical pin corrected the lower part of aiming at described baffle plate, and elastic cylindrical pin parallels with described dead bolt.
Wherein, when described elastic cylindrical pin turned to horizontal level, elastic cylindrical pin was vertical with described dead bolt.
Positive progressive effect of the present utility model is: interlock of the present utility model can guarantee reliably that switch-fuse combination cabinet and case become the interlocking between the net door, improve processing safety.
