Technical Field
The utility model belongs to the technical field of the equipment is ensured to the cubical switchboard, concretely relates to load switch unit operating device.
Background
The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters a main control switch in the cabinet and then enters a branch control switch, and each branch is arranged according to the requirement. Such as meters, automatic controls, magnetic switches of motors, various alternating current contactors, and the like, some of which are also provided with high-voltage chambers and low-voltage chamber switch cabinets, and high-voltage buses, such as power plants, and some of which are also provided with low-frequency load shedding for keeping main equipment.
According to southern grid requirements: solid insulation looped netowrk cabinet load switch cabinet, the operation mode does: the load switch is automatically switched on when the energy storage mechanism stores energy; the linkage requirements are as follows: when the isolating switch is in an opening state, the energy storage mechanism cannot be operated, namely, the load switch cannot be switched on.
The interlocking solution of mechanism of current solid insulation load switch cabinet is mostly: the soft chain is adopted, namely, the thin and flexible wires are adopted for transmission to pull the baffle, so that the following defects exist:
1. the soft silk rope is not fixed well, the clamping stagnation phenomenon is frequent, and the interlocking is not reliable;
2. the requirement of all-weather environment cannot be met, particularly, the mechanism often rusts in a humid environment, cannot be pulled when moving, and loses the interlocking function, so that misoperation of a high-voltage cabinet cannot be prevented, and huge potential safety hazards are brought.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a load switch unit operating device to solve the problem that proposes in the above-mentioned background art, provide a simple structure, it is few to dismantle the part, safe and reliable's chain mode.
In order to achieve the above purpose, the utility model adopts the following technical scheme: load switch unit operating device, including load switch operating device, energy storage motor, interlocking board, energy storage operating axis, first earthing switch operating device, isolator operating device and second earthing switch operating device, load switch operating device is located one side of first earthing switch operating device, the last energy storage motor of installing of load switch operating device, install isolator operating device on the first earthing switch operating device, the bottom that interlocking board is close to the energy storage operating axis has the lower convex part that shelters from the energy storage operating axis.
Further, a second grounding switch operating mechanism is installed on one side of the isolating switch operating mechanism.
Further, install protruding post on the lateral wall of energy storage motor, the spout that corresponds with protruding post is seted up to the inboard of interlock board.
Further, the sliding groove of the interlocking plate can slide left and right along the protruding column.
Further, the lower convex part and the interlocking plate are of an integrated structure.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses mechanical interlocking mode between load switch mechanism and the isolator mechanism has improved interlocking reliability greatly, satisfies southern electric wire netting requirement, and this interlocking mode is applicable to all-weather environment place simultaneously, provides the safety guarantee for preventing the maloperation of high-voltage board.
