Abstract
The utility model relates to a protecting cover plate structure of a circuit breaker of a locomotive. The protecting cover plate structure comprises a base and a protecting cover plate, wherein the protecting cover plate is an insulating cover plate and is installed on the base through a connecting part. According to the protecting cover plate of the circuit breaker of the locomotive, the insulating cover plate is used, so that the electric clearance between the circuit breaker and a cabinet body is increased, the safety of maintenance personnel during operation is improved, the protecting cover plate is not required to be grounded through a grounding wire, and the disassembly and the assembly during maintenance are facilitated.
Description
Technical field
The utility model relates to a kind of locomotive circuit breaker protective cover plate structure.
Background technology
The circuit breaker quantity that electric locomotive is installed is more, generally installs concentratedly in low-voltage electrical cabinet.Because circuit breaker will often be operated, and breaker connection head place is exposed.If do not take safeguard procedures, cause personal safety easily to operating personnel.
At present, the security protection of circuit breaker generally adopts metal cover board to protect, and this safeguard procedures cause between breaker connection head place and the protective cover plate under high height above sea level situation electric clearance not enough.In addition, the metallic safety protection cover plate must with cabinet ground connection, safeguard will dismantle protective cover plate with maintenance the time inconvenient at circuit breaker.
Summary of the invention
The purpose of the utility model is, to the deficiency of prior art, a kind of locomotive circuit breaker protective cover plate is provided, and increased the electric clearance between circuit breaker and the cabinet, and protective cover plate is for convenience detach.
The technical scheme of the utility model does, a kind of locomotive circuit breaker protective cover plate structure comprises base and protective cover plate, and said protective cover plate is an insulation cover plate, and protective cover plate is installed on the base through connector.
Protective cover plate adopts insulating material, with the electric clearance between increase circuit breaker and the breaker plate door, and need not make things convenient for dismounting with earth connection with its ground connection.
Handle is equipped with in the said protective cover plate outside, the dismounting of insulation cover plate during convenient the maintenance.
Said protective cover plate is having slotted eye with the breaker body corresponding position, so that let circuit breaker expose, and handled easily.
The inboard installing of said protective cover plate reinforcement, but the intensity of reinforced insulation cover plate.
According to the embodiment of the utility model, connector is selected bolt for use, easy accessibility.
Know by above; The utility model is as a kind of locomotive circuit breaker protective cover plate; Through adopting insulation cover plate, increased the electric clearance between circuit breaker and the cabinet, improved the safety of flight crew when operation; And need not adopt earth connection with its ground connection, make things convenient for the dismounting when Maintenance and Repair.
Description of drawings
Fig. 1 is the scheme of installation of the said locomotive circuit breaker of the utility model protective cover plate structure;
Fig. 2 is the structural representation of protective cover plate among Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of locomotive circuit breaker protective cover plate structure comprises base and protective cover plate 2, and protective cover plate 2 is an insulation cover plate, and its material is a glass cloth laminated sheet, and protective cover plate 2 is installed on the base 1 through connector 5.
Handle 4 is equipped with in protective cover plate 2 outsides, and protective cover plate 2 is having slotted eye 7 with breaker body 3 corresponding positions, protective cover plate 2 inboard installing reinforcements 6, and connector 5 is a bolt.
