Abstract
The utility model discloses a special-purpose mechanical characteristic test wire for a VD4 vacuum circuit breaker. The special-purpose mechanical characteristic test wire comprises a secondary plugging member and leads connecting the secondary plugging member, the leads used for connecting the secondary plugging member are three in number, the other ends of the three leads are respectively provided with a lead plug, and the lead plugs are respectively plugged with control outlets of a mechanical characteristic tester, and an outer side of the three leads connected with the secondary plugging member is sleeved by a protection tube. The special-purpose mechanical characteristic test wire realizes connection between the control outlets of the mechanical characteristic tester and a control loop of the VD4 vacuum circuit breaker and solves a problem of difficulty in testing mechanical characteristics of the VD4 vacuum circuit breaker.
Description
Technical field
This practicality belongs to the power equipment technical applications, specifically a kind of VD4 vacuum circuit breaker special-purpose machinery characteristic test line.
Background technology
After the isolating switch overhaul or in the situation such as mechanism's critical piece replacing, need to be to the mechanical characteristic test of isolating switch, the breaker mechanic property test event comprises low-voltage acting characteristic, actuation time, divide-shut brake speed.Usually, if the isolating switch operation voltage is too high or too low, just may cause isolating switch mistake separating brake and false switching, and refusal closes a floodgate when isolating switch breaks down, thereby cause the accident generation.
Isolating switch actuation time, speed are the major parameters that guarantees normal operation of circuit breaker and system safety operation, and the isolating switch action is too fast, easily causes the damage of circuit breaker components, shorten the serviceable life of isolating switch; The isolating switch bradypragia, can lengthen the quenching time, burn out contact, cause overstep tripping, increases the weight of the damage of equipment and affect the stable of electric system.
So, for parameters such as the operation voltage that guarantees isolating switch, divide-shut brake speed in normal range, need to after overhaul or the mechanism critical piece isolating switch after changing carry out mechanical characteristic test, carry out breaker mechanic property when test, the operating power output interface of tester, accumulation power supply etc. need to be connected to isolating switch is controlled accordingly, tank circuit.
Different from common isolating switch, VD4 type vacuum circuit breaker secondary circuit is integrated in secondary inserting piece inside, common mechanic character tester p-wire can't be used in conjunction with and carry out mechanical test with secondary inserting piece, and this mechanical property that just to the testing staff, detects VD4 type vacuum circuit breaker is brought very large inconvenience.
Summary of the invention
The technical matters that the utility model solves has been to provide a kind of VD4 vacuum circuit breaker special-purpose machinery characteristic test line, the utility model has realized that mechanic character tester controls being connected of outlet and VD4 vacuum circuit breaker control loop, has solved the problem of the testing mechanical characteristic difficulty of VD4 vacuum circuit breaker.
For solving the problems of the technologies described above, the utility model VD4 vacuum circuit breaker special-purpose machinery characteristic test line, it is characterized in that, the wire that comprises secondary inserting piece and connecting secondary plug-in unit, the wire of described connecting secondary plug-in unit is three, on the other end of described three wires respectively correspondence be provided with line trap, described line trap correspondence respectively is inserted in mechanic character tester and controls outlet.
The outer cover of three wires of described connecting secondary plug-in unit is equipped with protecting tube.
The beneficial effects of the utility model are: the utility model VD4 vacuum circuit breaker special-purpose machinery characteristic test line has thoroughly solved the problem of the testing mechanical characteristic difficulty of VD4 vacuum circuit breaker, has the advantages such as simple in structure, easy to make, economical and practical.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
In figure: 1-secondary inserting piece, 2-wire, 3-line trap, 4-protecting tube.
Embodiment
As shown in Figure 1, a kind of VD4 vacuum circuit breaker of the utility model special-purpose machinery characteristic test line, it comprises the wire 2 of secondary inserting piece 1 and connecting secondary plug-in unit, the wire 2 of described connecting secondary plug-in unit 1 is three, on the other end of described three wires respectively correspondence be provided with line trap 3, described line trap 3 is the corresponding control outlet that is inserted in mechanic character tester respectively.
The outer cover of three wires 2 of described connecting secondary plug-in unit 1 is equipped with protecting tube 4.Protecting tube 4 can, by three wire 2 collocateds, can prevent from being torn in use like this.
During use, only need wire one end that will be provided with secondary inserting piece 1 directly to be connected use with the secondary inserting piece arranged on the VD4 vacuum circuit breaker, the control that the other end that is provided with line trap 3 is connected to mechanic character tester exports the test that can realize the VD4 vacuum breaker mechanical features.
Except the described technical characterictic of above-mentioned instructions, be the known technology of those skilled in the art.
