Description
Technical field
The present invention relates to a kind of explosion-proof knife switch.
Background technology
Knife switch i.e. rated voltage, in 1kV and above disconnecting switch, often referred to simply as disconnecting switch, is that height presses off
Closing in electrical equipment and use most a kind of electrical equipment, the principles and structure of itself is fairly simple, but owing to usage amount is big, work
Making reliability requirement high, the impact on electric substation, the design of power plant, foundation and safe operation is the biggest.Disconnecting switch main
Feature is without arc extinguishing ability, can only divide, closes circuit in the case of not having load current.Disconnecting switch is used for each step voltage, uses
Making to change circuit connect or make circuit or equipment and isolated from power, it does not stop ability, can only first with miscellaneous equipment by circuit
Operate again after disconnection.Typically with the interlock of maloperation when preventing from switching on-load, it is sometimes desirable to pin prevents greatly
Fault magneticaction under disconnect switch.
Electric brake refers to the relatively large on and off switch of ratio, earth leakage circuit-breaker.Also referred to as plug-in strip.The operating principle of earth leakage circuit-breaker
It is: on an iron core, have a main winding and an auxiliary winding: main winding is divided into two windings that one of them is input electricity
Stream winding, another is output electric current winding.When without electric leakage, input current and output electric current are equal, two magnetic flux on iron core
Vector be zero, electromotive force would not be induced on auxiliary winding, induced voltage otherwise on auxiliary winding, will be had to be formed, amplified
It is pushed to actuator, makes switch trip.
Current existing knife switch does not possess explosion-proof effect, and structural stability is poor, installs inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compact conformation, and Stability Analysis of Structures is reliable, has explosion prevention function, behaviour
Make convenient explosion-proof knife switch.
For solving the problems referred to above, the present invention adopts the following technical scheme that a kind of explosion-proof knife switch, including base plate, inner shell
Body, shell body and plug-in strip, described inner housing is located on base plate, and described shell body is located at outside inner housing, described shell body and the end
Plate is hinged, and described plug-in strip end is provided with tool rest, and described plug-in strip is hinged with tool rest, and described plug-in strip top is hinged with shell body, institute
Stating tool rest side and be provided with cutter holder, described base plate two ends are provided with binding post, and described binding post is electrical with cutter holder and tool rest respectively
Connecting, described shell body side is provided with sleeve, is provided with reinforcement, is provided with manipulation in described sleeve outside described sleeve
Bar, described action bars end is provided with ball.
As preferably, described inner housing welds with base plate, keeps Stability Analysis of Structures reliable.
As preferably, described plug-in strip is arranged on inside shell body, keeps safe and reliable.
As preferably, described tool rest is fixing with base plate to be connected, and keeps structural stability high.
As preferably, described reinforcement and sleeve weld, lift structure intensity.
The invention have the benefit that inner housing and the shell body of setting have explosion prevention function, keep safely may be used when using
Lean on；Being provided with reinforcement outside the sleeve arranged keeps regulation reliable and stable, and structural strength is high；Arrange plug-in strip bottom and tool rest
Hinged, top is hinged with shell body, keeps compact conformation, convenient and reliable operation.

Inner housing 2 is located on base plate 1, and described shell body 3 is located at outside inner housing 2, and described shell body 3 is hinged with base plate 1, described plug-in strip
4 ends are provided with tool rest 5, and described plug-in strip 4 is hinged with tool rest 5, and described plug-in strip 4 top is hinged with shell body 3, described tool rest 5 one
Side is provided with cutter holder 6, and described base plate 1 two ends are provided with binding post 7, and described binding post 7 electrically connects with cutter holder 6 and tool rest 5 respectively
Connecing, described shell body 3 side is provided with sleeve 8, is provided with reinforcement 9, is provided with behaviour in described sleeve 8 outside described sleeve 8
Vertical pole 10, described action bars 10 end is provided with ball 11.
Described inner housing 2 welds with base plate 1.
Described plug-in strip 4 is arranged on inside shell body 3.
Described tool rest 5 is fixing with base plate 1 to be connected.
Described reinforcement 9 welds with sleeve 8.
The invention have the benefit that inner housing and the shell body of setting have explosion prevention function, keep safely may be used when using
Lean on；Being provided with reinforcement outside the sleeve arranged keeps regulation reliable and stable, and structural strength is high；Arrange plug-in strip bottom and tool rest
Hinged, top is hinged with shell body, keeps compact conformation, convenient and reliable operation.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
The change expected without creative work or replacement, all should contain within protection scope of the present invention.
