Abstract
The utility model discloses a low-voltage switch multifunctional protection device. The protection device comprises a lower box, wherein an upper cover is movably hinged to the lower box, wire pressing clamps are internally arranged at two ends of the bottom of the box, two sides of the box are provided with through holes, rubber rings are arranged in the through holes, and buckling wings are arranged on the periphery of the upper cover. According to the utility model, a low-voltage switch is disposed inside the box, and wires of two ends of the low-voltage switch are fixed by the wire pressing clamps, such that the electrified metal surfaces of an upper incoming wire and a lower outgoing wire are ensured to be within a protection range of the protection device, and electric shocks of maintenance personnel caused by touching naked electrified parts of adjacent low-voltage switches is prevented. The low-voltage switch multifunctional protection device improves the safety of live operation in a distribution system.
Description
Technical field
The utility model relates to low tension switch protection equipment technical field, relates in particular to a kind of low tension switch multifunctional protection device.
Background technology
In recent years, along with many new residential quarters continue to bring out, corresponding low-voltage distribution station is also built following closely and is put into operation, and the low tension switch of 0.4KV is also more and more, because the electric pressure of low tension switch has only 380V, just can guarantee safe distance not touching under the surface condition.So, when this type of switch is overhauled, often ignore the importance that safety measure is implemented, there is certain potential safety hazard.
Power distribution station is mainly based on switchyard, looped network station, open air station at present, wherein the open air station has accounted for more than 90% of power distribution station sum again, in the open air station mainly based on 0.4 kilovolt of low tension switch, when low tension switch of maintenance, the charged connecting portion of inlet wire and busbar is exposed outside on the adjacent low tension switch, following outlet and cable connection point expose outside too, and be very dangerous.Exist the potential safety hazard that the exposed live part of having touched adjacent low tension switch owing to the maintainer causes electric shock.
Simultaneously, to be in the position that busbar (cable) connects different because low tension switch passes in and out line when mounted up and down, cause the position of the exposed live part of the last inlet wire of low tension switch and following outlet to have discrepancy, existing protective cover can't be applicable to all low tension switches, run into the low tension switch of special circumstances, existing protective cover length can't be regulated, and may be difficult to all block, and still has to have the situation generation outside of live metal surface exposure.
The utility model content
The utility model provides a kind of safe, easy to use, effective low tension switch multifunctional protection device that uses.
A kind of low tension switch multifunctional protection device comprises lower box body, and described lower box body is provided with the loam cake of active link; described box body inner bottom part two ends are provided with the line ball folder; the both sides of described box body are provided with through hole, are provided with rubber ring in this through hole, and all sides of described loam cake are provided with the fastening wing.
The periphery of described lower box body is provided with groove, mosaic seal in the described groove.
Described loam cake is provided with the polymethyl methacrylate observation window.
Described box body one side is provided with handle.
The utility model is by being arranged on low tension switch in the box body, the lead at low tension switch two ends is fixed by the line ball clamping, and then guarantee that the live metal surface that low tension switch passes in and out line up and down is in the protection range of protector, causes electric shock because of the exposed live part of having touched adjacent low tension switch when having avoided the maintainer to operate; Described box body one side is provided with handle, and it is convenient for carrying; The both sides of described box body are provided with through hole, are provided with rubber ring in this through hole, and all sides of described loam cake are provided with the fastening wing, and the periphery of described lower box body is provided with groove, and mosaic seal in the described groove makes the box body good sealing effect; Therefore, the utility model has improved the fail safe of hot line job in the distribution system, simultaneously because the utility model protection tool reasonable in design, takes up an area of for a short time, makes the maintainer have enough spaces to carry out service work when overhauling.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; a kind of low tension switch multifunctional protection device comprises lower box body, and described lower box body is provided with the loam cake of active link; described box body inner bottom part two ends are provided with the line ball folder; the both sides of described box body are provided with through hole, are provided with rubber ring in this through hole, and all sides of described loam cake are provided with the fastening wing; the periphery of described lower box body is provided with groove; mosaic seal in the described groove, described loam cake is provided with the polymethyl methacrylate observation window, and described box body one side is provided with handle.
The utility model is by being arranged on low tension switch in the box body, the lead at low tension switch two ends is fixed by the line ball clamping, and then guarantee that the live metal surface that low tension switch passes in and out line up and down is in the protection range of protector, causes electric shock because of the exposed live part of having touched adjacent low tension switch when having avoided the maintainer to operate; Described box body one side is provided with handle, and it is convenient for carrying; The both sides of described box body are provided with through hole, are provided with rubber ring in this through hole, and all sides of described loam cake are provided with the fastening wing, and the periphery of described lower box body is provided with groove, and mosaic seal in the described groove makes the box body good sealing effect; Therefore, the utility model has improved the fail safe of hot line job in the distribution system, simultaneously because the utility model protection tool reasonable in design, takes up an area of for a short time, makes the maintainer have enough spaces to carry out service work when overhauling.
