Description
Technical field
This utility model relates to a kind of fuse box, particularly to a kind of railcar fuse box.
Background technology
Main fuse case is set at railcar top, is used for cutting off on car and fault between electrical equipment under car, prevent the short-circuit current touched net from causing the damage of vehicle arrangement or vehicle electric fault to cause the stoppage in transit on a large scale of running section.Existing fuse box form is airtight, and components and parts or the parts of box house are switched on lid when checking, this just safeguards to current check and brings very big inconvenience, adds maintenance cost.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of be easy to current check and safeguard, saves the railcar fuse box of regular maintenance cost.
For realizing object above, this utility model is achieved through the following technical solutions:
Railcar fuse box, described railcar fuse box may be provided at railcar top to be connected with pantograph, it is characterised in that including: insulated case and fuse；Described fuse is arranged in described insulated case；Described insulated case top is provided with transparency window can observe inside described insulated case.
Preferably, described railcar fuse box also includes support insulators；Described support insulators is arranged in described insulated case.
Preferably, described railcar fuse box also includes copper bar.Described copper bar is arranged in described insulated case and is set to be connected with described fuse.
Preferably, described railcar fuse box also includes securing member, described securing member to be set to described copper bar being connected the fastening of this copper bar being arranged in described insulated case.
Preferably, described railcar fuse box also includes blown fuse indicator, and this blown fuse indicator is set to face with described transparency window, and this blown fuse indicator is used for indicating whether described fuse fuses.
Preferably, described railcar fuse box also includes that air bleeding valve, described air bleeding valve are arranged on the bottom of described insulated case；Described air bleeding valve is check valve, and the outlet of this check valve is provided towards the outside of described insulated case.
Preferably, insulated case described in described railcar fuse box includes upper cover and casing；Described casing has cavity volume；Described upper cover is arranged on described casing to seal the cavity volume of this casing；Described transparency window is arranged on described and covers.
Preferably, it is set to hasp between upper cover with described casing described in described railcar fuse box be connected.
Preferably, described railcar fuse box also includes that waterproof grommet, described waterproof grommet are arranged between described upper cover and described casing.
Preferably, described railcar fuse box also includes the shock absorber part that insulate, and described insulation shock absorber part is arranged in described insulated case, and described insulation shock absorber part is set to be connected with described fuse to reduce the external force impact to this fuse.
The fuse box that this utility model provides, it is simple to regular maintenance inspection, it is to avoid the personal injury that maloperation causes, it is simple to good airproof performance while dampness and solidifying water are discharged in casing, prevents rainwater from sputtering.The observation window of described railcar fuse box can be observed box house securing member and connect the best, if having condensation hydrops and fuse state.It addition, the waterproof grommet of case lid is consumable accessory, opens every time and all must change, thus described railcar fuse box decreases the replacing of sealing member, saves manpower and material cost.

Fig. 1 is the structural representation of railcar fuse box of the present utility model.
Fig. 2 is the main perspective diagram of the railcar fuse box of Fig. 1.
Fig. 3 is the side perspective diagram of the railcar fuse box of Fig. 1；
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
As shown in Figure 1, Figure 2 and Figure 3, railcar fuse box includes casing 1, upper cover 2, transparency window 3, fuse 4, insulation shock absorber part 5, air bleeding valve 6, hasp 7.Fasten by hasp 7 and lock between casing 1 and upper cover 2.Fuse 4 is connected on casing 1 inner copper line, and is fixed on insulation shock absorber part 5.Transparency window 3 is had on upper cover 2.Air bleeding valve 6 is positioned at bottom casing 1.Described fuse 4 can be main fuse.As required, described fuse 4 can be at least one group.In the present embodiment, described insulated case includes casing 1 and upper cover 2.
Described casing 1 is installed on railcar top, is connected with pantograph, is also provided with support insulators, copper bar in casing 1.Described fuse 4 is connected with the copper bar in described casing 1.Casing 1 is installed on vehicle roof, and described insulation shock absorber part 5 disclosure satisfy that requirement is impacted in vehicle operational shock.
Described transparency window 3 can use the material such as clear glass or plastics to make.Vehicle is stopped transport cannot understand fuse state by electric signal when overhauling, and the blown fuse indicator that can observe fuse 3 by described transparency window 3 determines fuse 3 state, can check the copper bar securing member connection within casing 1 simultaneously.Casing is outdoor installation, seals waterproof, to meet waterproof requirement by arranging waterproof grommet practice between described casing 1 and described upper cover 2.
Described railcar fuse box also includes the air bleeding valve 6 being arranged on the bottom of casing 1.Railcar top is located at by casing, when vehicle from from ground to when running between at the bottom of ground, because variations in temperature can form solidifying water or steam in casing, electrical equipment in casing 1 is caused a hidden trouble.Solidifying water can be discharged outside casing 1 by air bleeding valve 6, or steam is discharged outside casing 1 by the hyperbar in casing 1.Air bleeding valve 6 is one-way valve designs simultaneously, prevents rainwater to be sputtered onto in casing 1.
In the present embodiment, described upper cover 2 uses hasp 7 to be connected with casing 1, can padlock, conveniently uncap maintenance while also avoid maloperation to cause personal injury.
Embodiment in this utility model is only used for illustrating this utility model, is not intended that the restriction to right, those skilled in that art it is contemplated that other replacements being substantially equal to, all in this utility model protection domain.
