Description
Technical field
This utility model is related to technical field of electric equipment, more particularly to a kind of visual breakpoint isolated switchgear.
Background technology
Visual breakpoint isolated switchgear is that all kinds of enterprises are pacified as to the field service personnel person during overhaul of the equipments
A kind of high isolation switch device of full protection grade, its usage frequency is higher, using site environment very severe, so needing
Will its have intuitively visual, safe and reliable, degree of protection is high, easy to use the features such as.
With the requirement to power safety of continuous development and country of electric utility, in existing isolated switchgear generally
Use common disconnecting switch, common disconnecting switch does not have safety interlocking control, no matter cause switch to be in one kind opening
Close division, isolated switchgear can be opened, and also can continue disconnecting switch operation after chamber door is opened, so that disconnecting switch is lost
Go due effect, do not have a buffer action, poor safety performance, along with protective measure is not adopted due to switch casing,
Degree of protection quite poor, is unfavorable for the safe handling of power supply, particularly in harsh environments, can not reach related wanting
Ask.
Utility model content
This utility model, mainly solving the technical problems that providing a kind of visual breakpoint isolated switchgear, ensure that electricity
The safeguard protection effect in source, makes disconnecting switch really play buffer action.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is：There is provided a kind of visual breakpoint every
From switchgear, including casing and chamber door, described casing and chamber door are rotatedly connected, and are provided with switch installation board in described casing,
It is provided with switch installation board and be provided with and can observe on the visual disconnecting switch in contact and the chamber door corresponding with disconnecting switch
The window of disconnecting switch breakpoint, is provided with anti-guard housing between described disconnecting switch and described chamber door, described anti-guard housing is provided with axis hole, institute
State and in axis hole, be provided with switching manipulation axle, one end of described switching manipulation axle is arranged on the behaviour of described disconnecting switch through described axis hole
Make in axle sleeve, make described disconnecting switch separating brake or combined floodgate, the other end of described switching manipulation axle is polygon, and with described axis hole
Opening keep certain distance, the outside of described chamber door is rotatably connected and has operation handle, and described operation handle sets inside chamber door
There are locking plate and extension, described locking plate can rotate with described operation handle, and described extension is provided with and described switching manipulation
The jack that axle matches, when described chamber door is closed, described extension inserts in described axis hole, and described switching manipulation axle inserts institute
State in jack, when rotating described operation handle, described locking plate can be locked or open described chamber door.
It is different from the situation of prior art, the beneficial effects of the utility model are：Observable is not only provided with chamber door
The window of breakpoint, and the operation handle on chamber door disconnecting switch could be operated only when chamber door is closed so that every
Just can open from chamber door when switching off, and chamber door is opened rear disconnecting switch and can not be closed a floodgate, only after chamber door is shut, switch
Ability switch closing and switch opening, such that it is able to ensure the safeguard protection effect of power supply, makes disconnecting switch really play buffer action, improves
The degree of protection of isolated switchgear.
Brief description
Fig. 1 is the structural representation of this utility model embodiment visual breakpoint isolated switchgear.
Fig. 2 is the schematic cross-section of the switching manipulation axle of this utility model embodiment visual breakpoint isolated switchgear.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, it is the structural representation of this utility model embodiment visual breakpoint isolated switchgear.The present embodiment
Visual breakpoint isolated switchgear includes casing 1 and chamber door 2, and casing 1 and chamber door 2 are rotatedly connected, and is provided with switch peace in casing 1
Dress plate 3, switch installation board 3 is provided with and installs on the visual disconnecting switch in contact 4 and the chamber door 2 corresponding with disconnecting switch 4
There is the window 21 that can observe disconnecting switch breakpoint, between disconnecting switch 4 and chamber door 2, be provided with anti-guard housing 5, anti-guard housing 5 is provided with axle
Hole 51, is provided with switching manipulation axle 6 in axis hole 51, one end of switching manipulation axle 6 is arranged on the operation of disconnecting switch 4 through axis hole 51
In axle sleeve, make disconnecting switch 4 separating brake or combined floodgate, the other end of switching manipulation axle 6 is polygon, and keep with the opening of axis hole 51
Certain distance, the outside of chamber door 2 is rotatably connected operation handle 7, and operation handle 7 is provided with locking plate 71 inside chamber door 2 and extends
Portion 72, locking plate 71 can rotate with operation handle 7, and extension 72 is provided with the jack 73 matching with switching manipulation axle 6, works as case
When door 2 is closed, in extension 72 insertion axis hole 51, in switching manipulation axle 6 insertion jack 73, when rotating operating handle 7, locking plate
71 can be locked or open chamber door 2.
In the present embodiment, one end that switching manipulation axle 6 is matched with jack 73 is hexagon, as shown in Fig. 2 so that
Operation handle 7 has enough torque rotation switching manipulation axles 6.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
