Abstract
The invention discloses a circuit breaker possessing a closed insulation shell. The circuit breaker comprises an operating mechanism and the closed insulation shell. The insulation shell is fixed to an operating mechanism box. An insulation pull rod is arranged in an enclosed space of the insulation shell. The insulation pull rod is fixed to a mechanism in the operating mechanism box. A vacuum arc-extinguishing chamber and a mutual inductor are fixed to two ends of the insulation pull rod. A lead wire of the mutual inductor is directly introduced into the operating mechanism box in the insulation shell. Incoming and outgoing line terminals of the circuit breaker are fixed to two sides of the insulation shell. An umbrella skirt is arranged between the incoming and outgoing line terminals of the insulation shell. An outer side of a connection portion of the insulation shell and the operating mechanism box is provided with the umbrella skirt. The circuit breaker has advantages that the size is small; weight is light; the box body adopts an insulating material; incoming and outgoing lines are directly installed on an outer side of an insulation box body and extra insulation processing is not needed; an incoming and outgoing line distance is greatly shortened; because the box body is insulated, the mutual inductor is directly casted and installed in the box body; the lead wire of the mutual inductor is located in the box body and extra insulation processing is not needed.
Description
Technical field
The present invention relates to field of electrical equipment, a kind of chopper.
Background technology
Existing chopper generally comprises column support type chopper and common box type chopper；The structure of column support type chopper such as figure
Shown in 3, transformer is sleeved on vacuum interrupter, and transformer volume is relatively big, higher to transformer request, due to subject to conditions
Can not install polytropic ratio transformer and ZCT, the exposed needs outside of transformer does corresponding insulation processing, and the life-span is shorter.
Transformer exposed the needs outside of lead-in wire does insulation processing.
As shown in Figure 4, housing uses metal material to the structure of common box type chopper, and weight is big, on-insulated；Line needs
Insulate with housing, and leave the creep age distance of necessity, make switch size excessive；The transformer of switch internal and vacuum interrupter are all
Need to do corresponding insulation with housing, and leave corresponding insulation distance.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of volume little, lightweight；Breaking of Threephase common-box
Road device, concrete technical scheme is as follows:
A kind of have the chopper closing insulation shell, including operating mechanism, also includes the insulation shell closed, described absolutely
Edge housing is fixed on operating mechanism case, arranges insulated tension pole in the closing space of insulation shell, and described insulated tension pole is fixed on
In mechanism in operating mechanism case；The two ends of described insulated tension pole fix vacuum interrupter and transformer respectively；Described transformer
Lead-in wire be introduced directly in insulation shell inside operating mechanism case；The line terminal of chopper is separately fixed at insulation shell
Both sides；Between the line terminal of insulation shell, full skirt is set；Outside at insulation shell Yu operating mechanism case coupling part
It is also provided with full skirt.
Described insulation shell is made up of left and right two parts, and is combined into by left and right two parts insulation shell with bolt and nut
Integrally.
The every side of described insulation shell arranges 3 chambers, and vacuum interrupter or transformer are arranged in described chamber.
The invention have the advantage that volume is little, lightweight；Casing uses insulant, and line is directly mounted at insulated case
External side, it is not necessary to especially do insulation processing；It is greatly shortened line distance；Transformer is built-in, and owing to casing insulate, transformer is straight
Connect to water and be loaded in casing.Transformer goes between at box house, it is not necessary to do especially insulation processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural representation of column support type chopper；
Fig. 4 is the structural representation of common box type chopper.
Detailed description of the invention
Illustrating the present invention below in conjunction with the accompanying drawings, as shown in Figure 1 and Figure 2, the present invention includes operating mechanism case 8, also includes
The insulation shell 1 closed, described insulation shell 1 is fixed on operating mechanism case 8, arranges absolutely in the closing space of insulation shell 1
Edge pull bar 6, described insulated tension pole 6 is fixed in the mechanism in operating mechanism case 8；The two ends of described insulated tension pole 6 are fixed respectively
Vacuum interrupter 2 and transformer 3；The lead-in wire 5 of described transformer 3 is introduced directly into inside operating mechanism case 8 in insulation shell 1；
The line terminal 4 of chopper is separately fixed at the both sides of insulation shell 1；Between the line terminal of insulation shell 1, umbrella is set
Skirt 7；It is also provided with full skirt 7 in the outside of insulation shell 1 with operating mechanism case 8 coupling part.
Described insulation shell 1 is made up of left and right two parts, and is combined by left and right two parts insulation shell with bolt and nut
Integral.
The described every side of insulation shell 1 arranges 3 chambers 9, vacuum interrupter 2 or transformer 3 and is arranged on described chamber 9
In.Owing to casing insulate, transformer housing can directly water and be loaded in casing.
Vacuum interrupter 2 and transformer 3 have not only been carried out well by the structure of the present invention relative to column support type chopper
Protection, and vacuum interrupter 2 and transformer 3 are separately positioned on the two ends of insulated tension pole, it therefore reduces the size of transformer
And requirement；Additionally, protect transformer lead-in wire, it is not necessary to carry out protection especially；
The present invention, relative to common box type chopper, owing to have employed insulation shell, and is provided with full skirt, therefore, and line
Terminal is made without insulation processing especially, reduces the volume of chopper；The transformer of switch internal and vacuum interrupter
All need not do corresponding insulation with housing, reduce manufacturing cost.
