Abstract

The utility model discloses a do benefit to radiating C-GIS and use insulating splint structure, including the explosion chamber, the both sides of explosion chamber are equipped with insulating splint, go up the support of being qualified for the next round of competitions and link to each other with the quiet end of explosion chamber, and the support of being qualified for the next round of competitions passes through the flexible coupling and links to each other with the movable end of explosion chamber down. The other end of the insulating pull rod is connected with the corrugated pipe, and the other end of the corrugated pipe is connected with the mechanism through a screw rod. Change traditional structural style, adopt the splint structure, convenient assembling, with low costs, it is penetrating from top to bottom, return circuit resistance reduces, changes the structure simultaneously, does benefit to the heat dissipation, promotes the performance of l circuit breaker.

Description

Do benefit to radiating C-GIS and use insulating splint structure
Technical Field
The utility model relates to a middling pressure electric power becomes distribution system, especially relates to a do benefit to radiating C-GIS and use insulating splint structure.
Background
Circuit breakers function to carry, open, and close current in an electrical power distribution system. At present, most of circuit breakers related to a medium-voltage power system adopt a vacuum breaking technology, and a core component vacuum arc extinguish chamber is an important component of the circuit breaker.
The current insulation cylinder for the C-GIS has two main modes:
firstly, the embedded pole structure is high in cost and not beneficial to heat dissipation of the product;
the other type is an integrally formed insulating cylinder structure, so that the assembly is inconvenient, and the heat dissipation is also not facilitated in the aspect of temperature rise.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a do benefit to radiating C-GIS and use insulating splint structure.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a do benefit to radiating C-GIS and use insulating splint structure, including the explosion chamber, the both sides of explosion chamber are equipped with insulating splint, and the support of being qualified for the next round of competitions links to each other with the quiet end of explosion chamber on, and the support of being qualified for the next round of competitions passes through the flexible coupling and links to each other with the movable end of explosion chamber down.
By the above technical scheme the utility model provides a can see out, the embodiment of the utility model provides a do benefit to radiating C-GIS and use insulating splint structure changes traditional structural style, adopts the splint structure, and convenient assembling, with low costs are penetrating from top to bottom, do benefit to the heat dissipation.
Drawings
Fig. 1 is the embodiment of the present invention provides a schematic diagram of an insulating clamping plate for a C-GIS, which facilitates heat dissipation.
In the figure:
1. the device comprises an upper outgoing line support, 2 insulating clamping plates, 3 lower outgoing line support, 4 flexible connection, 5 corrugated pipes, 6 insulating pull rods and 7 arc extinguish chambers.
Detailed Description
Embodiments of the present invention will be described in further detail below. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
The utility model discloses a do benefit to radiating C-GIS and use insulating splint structure, the concrete implementation mode of its preferred is:
the arc extinguishing chamber is characterized by comprising an arc extinguishing chamber, wherein insulating clamping plates are arranged on two sides of the arc extinguishing chamber, an upper outgoing line support is connected with a static end of the arc extinguishing chamber, and a lower outgoing line support is connected with a movable end of the arc extinguishing chamber through flexible connection.
The other end of the insulating pull rod is connected with the corrugated pipe, and the other end of the corrugated pipe is connected with the mechanism through a screw rod.
One end of the corrugated pipe, which is provided with the screw rod, is in dynamic seal with the air box through the flange.
The utility model discloses a do benefit to radiating C-GIS and use insulating splint structure changes traditional structural style, adopts the splint structure.
The assembly is convenient, the cost is low, the upper part and the lower part are through, and the heat dissipation is facilitated. The heat dissipation effect is good, and the performance of the circuit breaker is improved;
the conductive clamp is removed, the flexible connection is directly connected with the movable end of the arc extinguish chamber, the traditional flexible connection structure is changed, the stress is small, the looseness is not easy to occur, the performance is more reliable, the cost is reduced, and the installation is convenient.
The loop resistance is reduced, and the structure is changed, thereby being beneficial to heat dissipation.
The specific embodiment is as follows:
as shown in fig. 1, the upper outgoing line bracket 1 is connected with the static end of the arc extinguish chamber 7, the flexible connection 4 is directly connected with the movable end of the arc extinguish chamber 7, and the other end of the flexible connection 4 is connected with the lower outgoing line bracket 3. The insulating pull rod 6 is connected with the movable end of the arc extinguish chamber 7, and the other end of the insulating pull rod 6 is connected with the corrugated pipe 5. (the flange of the bellows 5 and the air box realize the dynamic seal of the air box, the screw rod of the bellows 5 is connected with the mechanism)
When the connection needs electricity, the mechanism drives the corrugated pipe 5 to move, the corrugated pipe 5 drives the insulating pull rod 6 connected with the corrugated pipe to move, and the insulating pull rod 6 plays an insulating role at the same time, so that the movable end of the arc extinguish chamber is insulated from the mechanism. The insulating pull rod 6 drives the movable end of the arc extinguish chamber 7 to move simultaneously, so that the movable contact and the fixed contact inside the arc extinguish chamber are contacted, and the switching-on power transmission is realized.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
