Abstract
The utility model relates to a novel valve elevating mechanism for a DC switch cabinet, belonging to the field of DC traction power supply device, comprising a guide arm, a linkage rod and a valve, wherein one end of the guide arm is connected with the linkage rod, the linkage rod is fixed on the valve through a bolt, and the guide arm and the linkage rod are both prepared by an SMC composite material. The novel valve elevating mechanism for a DC switch cabinet is mounted on a framework, and then it is inspected that whether the elevation movement of the valve is flexible or not and whether the position of the linkage mechanism is in place or not. The novel valve elevating mechanism for a DC switch cabinet overcomes the defects that the linkage support prepared by a metal material is easily corroded and is bad in insulation performance, and can endure a high temperature of more than 220 DEG C, thereby enabling equipment safety and stability to be greatly increased.
Description
Technical field
The utility model relates to the direct-current traction power supply apparatus field, is specifically related to a kind of new DC switch cubicle valve elevating mechanism.
Background technology
The valve elevating mechanism of direct-current switch cabinet is as mechanical composition part important in the direct-current switch cabinet, and it is made up of three parts of valve of leading arm made of iron, gangbar and insulation PC material.Function at the dc circuit breaker handcart when withdrawing from the position, can avoid operating personnel to touch the charged bus at rear.Direct-current switch cabinet valve elevating mechanism material is generally the linkage support of metal material.The linkage support of metal can have high strength, high temperature resistant and fire-retardant characteristics, but also has shortcoming clearly: under the situation of the big current failure tripping operation of dc circuit breaker, the electric arc that circuit breaker ejected may make direct-current switch cabinet valve elevating mechanism charged; Valve mechanism is with the insulation of the tank bracket of direct current cabinet at ordinary times; But if situation is more serious, electric arc can dwindle the insulation distance between air with air ionization (moist environment is particularly evident) greatly; Will cause the tank bracket of direct current cabinet also simultaneously charged; Not only frame protection be can cause, whole DC traction station and the outage simultaneously of adjacent station, the personal safety that also can endanger operating personnel made.
Summary of the invention
The purpose of the utility model provides a kind of new DC switch cubicle valve elevating mechanism; It has solved the shortcoming that linkage support is perishable, insulation is poor of metal material; And it is high temperature resistant can to reach more than 220 ℃, has improved the fail safe and the stability of equipment greatly.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises leading arm 1, gangbar 2, valve 3; One end of leading arm 1 is connected with gangbar 2, and gangbar 2 is through being bolted on the valve 3.
Described leading arm 1 all adopts the SMC composite material to process with gangbar 2.
The utility model is installed on the skeleton, and whether the lifting moving of inspection valve is flexible, and whether the position of link gear puts in place.
The utlity model has following beneficial effect: solved the shortcoming that linkage support is perishable, insulation is poor of metal material, and its high temperature resistant can reaching more than 220 ℃, improved the fail safe and the stability of equipment greatly.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises leading arm 1, gangbar 2, valve 3; One end of leading arm 1 is connected with gangbar 2, and gangbar 2 is through being bolted on the valve 3.
Described leading arm 1 all adopts the SMC composite material to process with gangbar 2.
This embodiment is installed on the skeleton, and whether the lifting moving of inspection valve is flexible, and whether the position of link gear puts in place.
This embodiment has solved the shortcoming that linkage support is perishable, insulation is poor of metal material, and its high temperature resistant can reaching more than 220 ℃, has improved the fail safe and the stability of equipment greatly.
