Description

A kind of vacuum circuit breaker fault determining device

Technical field

The utility model belongs to metallurgical technology field, particularly relates to a kind of vacuum circuit breaker fault determining device.

Background technology

Smelter electric furnace smelting power supply-distribution system, according to smelting process, generally by vacuum circuit breaker divide, make and break is opened or plugged, so the action of isolating switch is very frequent.In the normal smelting situation, single stove isolating switch action is more than 10 times, and failure rate is high.Circuit breaker failure is usually caused by external control loop fault or the fault of isolating switch own.It is lower that isolating switch is nonserviceabled, and the maintainer will be by checking control section and isolating switch itself, the failure judgement reason, often the processing time long, affect production.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of vacuum circuit breaker fault determining device, can help the maintainer to judge fast the fault coverage of vacuum circuit breaker, reduces fault handling time, thereby lowers the impact that fault causes production.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of vacuum circuit breaker fault determining device is provided, comprise casing, terminal row, power switch, on/off switch button, on/off switch pilot lamp, aviation plug, crocodile clip, but described casing top is provided with the case lid of folding, accommodating terminal row, power switch in the described casing; Described terminal row one end connects respectively on/off switch button, on/off switch pilot lamp, and the other end connects aviation plug, described power switch one end splicing ear row, and the other end connects crocodile clip.

Described casing and case lid formed shape are the hollow control box of rectangular parallelepiped.

Be connected by hinge between described casing and the case lid.

Described casing one side top edges is provided with the take-up groove.

Described take-up groove is rectangle.

Described casing one side is provided with handle.

Described casing one side is provided with some wire holes.

Described terminal row connects aviation plug by the control flexible cord.

Described power switch connects crocodile clip by power lead.

Beneficial effect

The utility model can help the maintainer to judge fast the fault coverage of vacuum circuit breaker, reduces fault handling time, thereby lowers the impact that fault causes production, and apparatus structure is reasonable and succinct, cost is low, making and easy to operate, practical.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.

Such as Fig. 1~shown in Figure 2, the utility model comprises casing 1, terminal row 3, power switch 2, on/off switch button 4, on/off switch pilot lamp 5, aviation plug 6, crocodile clip 8, but described casing 1 top is provided with the case lid 13 of folding, described casing 1 interior accommodating terminal row 3, power switch 2; Described terminal row 3 one ends connect respectively on/off switch button 4, on/off switch pilot lamp 5, and the other end connects aviation plug 6, described power switch 2 one end splicing ears row 3, and the other end connects crocodile clip 8.

Described casing 1 is the hollow control box of rectangular parallelepiped with case lid 13 formed shapes.

Be connected by hinge 14 between described casing 1 and the case lid 13.

Described casing 1 one side top edges are provided with take-up groove 11.

Described take-up groove 11 is rectangle.

Described casing 1 one sides are provided with handle 9.

Described casing 1 one sides are provided with some wire holes 10.

Described terminal row 3 connects aviation plug 6 by control flexible cord 12.

Described power switch 2 connects crocodile clip 8 by power lead 7.

The utility model is used for the judgement that the smelting process vacuum circuit breaker refuses to close, refuse minute fault coverage.Vacuum circuit breaker to be measured is dragged to outside the high-voltage board, aviation plug 6 is connected the aviation plug base of vacuum circuit breaker to be measured; Terminal row 3 one ends link to each other with aviation plug 6 by control flexible cord 12, and the other end connects respectively on/off switch button 4, the on/off switch pilot lamp 5 on the case lid 13; Vacuum circuit breaker to be measured closes, independent power source connects power switch 2 behind the crocodile clip 8 of power lead 7 ends, power lead 7; Press switch knob, the opening button of vacuum circuit breaker fault determining device, if vacuum circuit breaker to be measured closes, minute action is normal, illustrate that vacuum circuit breaker to be measured refuses to close or refuse a minute fault and belong to the external control loop fault, the non-fault of vacuum circuit breaker to be measured own, otherwise belong to the fault of vacuum circuit breaker to be measured own; The effect of take-up groove 11 is that test can be with in power lead 7 and the aviation plug 6 income take-up grooves 11 after finishing.
