Description
Technical field
This utility model relates to air switch technical field, particularly relates to the air switch of a kind of band transparent insulation cover.
Background technology
Air switch (hereinafter referred to as " sky is opened "), has another name called air-break, is the one of chopper.It is to return at low-voltage distribution
Lu Zhong, decapacitation complete contact and disjunction circuit outside, moreover it is possible to automatic shutoff circuit electric current exceed rated current thus protective loop and
Equipment.Due to sky open safe and reliable, it is widely used in low-voltage electrical loop, the most also plays emphatically in electric loop simultaneously
The effect wanted.Common sky is opened, and mainly has insulation crust, connects the screw of wire, rotating operation handle and deciliter finger
Show lamp.Sky was opened screw crimping lead wire and was accessed electric loop, and then rotating operation handle can deciliter electric loop.Work as instruction
Lamp closes for representing time red, represents disconnection time green.
Sky is opened in low-voltage electrical loop and is widely used, and especially in the various systems in power station, sky is opened and the most everywhere may be used
See.The substantial amounts of electric control system in power station needs to safeguard and maintenance, safeguards and in maintenance process, needs the quarantine measures such as power failure,
To ensure the safety of attendant.The most usually by the empty mode opened of disconnection as quarantine measures, forbid maintainer in operation
Mistiming touches rotating operation handle, and conjunction sky is opened and caused personnel to get an electric shock by mistake.Sometimes, having a lot of sky to open in same cupboard, some sky is opened
As the control of miscellaneous equipment, during this cabinet upkeep operation, these skies are opened to do and are isolated, to prevent maintainer from touching in operation mistiming
Rotating operation handle, a point sky is opened and is caused other unrelated equipment to stop transport by mistake.
Utility model content
This utility model is devoted to design a kind of need and makees the air switch of safe isolation belt transparent insulation cover, as operated sky
During the handle opened, insulating boot is opened, operated insulating boot on bonnet, can effectively prevent attendant's operation mistiming from dividing or miss
Conjunction sky is opened, and eliminates and there may be the potential safety hazard to people and equipment.Meanwhile, this design is simple, cheap, does not affect sky and opens auxiliary
The installation of adjuvant grafting point, can drive the simple transformation of row into according to the sky of different model, it is simple to sky is opened manufacturer and changed design batch production.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that a kind of band transparent insulation cover
Air switch, it includes insulating boot, and the bottom, left side of described insulating boot is provided with rotating shaft, and described rotating shaft is arranged on inside through hole
And fix by being arranged on the spring stop piece at rotating shaft two ends, described through hole processes the left end at air switch, described insulating boot
The other end is arranged on inside grooves, and described Pocket Machining is at the right-hand member of air switch, and described inside grooves is provided with two projections,
The opening edge of described insulating boot is between two projections, and described insulating boot is internally provided with rotating operation handle, described insulation
Match with four square grooves of air switch end face in four limits of cover.
The inside of described insulating boot is additionally provided with a deciliter display lamp, and the both sides external of described insulating boot is also equipped with wiring spiral shell
Silk.
Described insulating boot uses U-shape structure, and uses transparent plastic material to make.
This utility model has the advantages that:
The air switch of this utility model design, by conventional sky is opened increase transparent insulation cover, can effectively prevent from safeguarding
Personnel's operation mistiming is divided or conjunction sky is opened by mistake, eliminates and there may be the potential safety hazard to people and equipment.Meanwhile, can be only to important
Sky opens installation, can play good warning function.It addition, this design is simple, cheap, do not affect sky and open auxiliary contact
Install, the simple transformation of row can be driven into according to the sky of different model, it is simple to sky is opened manufacturer and changed design batch production.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is overall structure front view of the present utility model.
Fig. 2 is overall structure top view of the present utility model.
Fig. 3 is A partial view in this utility model Fig. 1.
In figure: insulating boot 1, rotating shaft 2, spring stop piece 3, through hole 4, groove 5, protruding 6, rotating operation handle 7, four square groove 8,

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As Figure 1-3, the air switch of a kind of band transparent insulation cover, it includes insulating boot 1, a left side for described insulating boot 1
Bottom, side is provided with rotating shaft 2, and it is internal and solid by being arranged on the spring stop piece 3 at rotating shaft 2 two ends that described rotating shaft 2 is arranged on through hole 4
Fixed, described through hole 4 processes the left end at air switch, and it is internal that the other end of described insulating boot 1 is arranged on groove 5, described groove 5
Processing the right-hand member at air switch, described groove 5 is internally provided with two projections 6, and the opening edge of described insulating boot 1 is positioned at two
Between protruding 6, described insulating boot 1 is internally provided with rotating operation handle 7；Four limits of described insulating boot 1 and air switch end face
Four square grooves 8 match.
Further, the inside of described insulating boot 1 is additionally provided with deciliter display lamp 10, the both sides external of described insulating boot 1
It is also equipped with terminal screw 9.It is attached with power line by terminal screw 9 is convenient.
Further, described insulating boot 1 uses U-shape structure, and uses transparent plastic material to make.By using transparent material
Material is made to conveniently observe the state of insulating boot 1 internal switch and then check its state easily.Improve safety, it is ensured that
The convenience of operation.
Specific works process of the present utility model and operation principle be:
When needs operation rotating operation handle, transparent plastic insulating boot is opened.After having operated, transparent plastic is exhausted
Edge cover is in closing.The rotating operation handle isolation that can be opened by sky, effectively prevents attendant's operation mistiming from dividing or misses
Conjunction sky is opened, and staff also there is no concern that touch sky opens by mistake, also there is no concern that operation mistake.Simultaneously as plastic insulation cover is than sky
Open little, the most do not hinder what sky opened to be mounted side by side.
Above-described embodiment is used for illustrating this utility model rather than limiting this utility model, in this practicality
In novel spirit and scope of the claims, any modifications and changes that this utility model is made, both fall within this reality
With novel protection domain.
