The utility model belongs to mid-cabinet VD4 switch test equipment.
Background technology
In the existing mid-cabinet, the precondition that VD4 type switch can carry out the switching characteristic test is: switch is divide-shut brake normally.The test method of VD4 type switching characteristic test is: wiring on the switch aviation plug, remove the VD4 switch panel, and manually remove closing locking, manually energy storage.
Original when test: 1. VD4 switch aviation plug is connected the switch cubicle aviation plug, high voltage switch tester wiring from the switch cubicle, shortcoming: to disconnect line on the switch cubicle, time-consuming, produce hidden danger; The high voltage switch tester signal seals in the switch cubicle straight-flow system, dangerous, hidden danger.2.VD4 the switch aviation plug breaks away from switch cubicle, takes panel apart, manually energy storage, and manual unlocking, wiring from the aviation plug of VD4 switch, shortcoming: time-consuming, plug line taking mistake is easily bumped, and damages VD4 switch Inside coil, and testing crew is dangerous simultaneously.
The technological deficiency that existing method of testing exists is: workload is big, inefficiency and be prone to cause potential safety hazard.
Summary of the invention
Big in order to overcome the workload that has mid-cabinet VD4 switch test equipment now; Inefficiency and be prone to cause the deficiency of potential safety hazard, the utility model provides a kind of mid-cabinet VD4 switching characteristic test unit that reduces workload, promotes work efficiency and eliminate safe hidden trouble.
The utility model solves the technical scheme that its technical matters adopted:

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, a kind of mid-cabinet VD4 switching characteristic test unit, said mid-cabinet VD4 switch are provided with male 1 of aviation plug; Said test unit also comprises and peg graft female 2 of the aviation plug of coupling of said male head; Female 2 of said aviation plug is connected with male 1 of said aviation plug, and each electric connection point that said aviation plug is female 2 all is connected with lead end, and said test unit also comprises power supply box; Said power supply box comprises switching manipulation direct supply and testing integrated circuits; Said switching manipulation direct supply is connected with testing integrated circuits, and said testing integrated circuits is provided with interface end, and said interface end is connected with said lead segments.
Said interface end comprises energy storage interface, locking interface, combined floodgate interface, separating brake interface and common interface.Each lead segments is provided with lug, and said lug is installed on the said interface end.
In the present embodiment; The aviation plug that is connected with the VD4 switch in the structure of the female head of aviation plug and the mid-cabinet is identical; In addition; Electric connection point between male head of aviation plug and the female head of aviation plug, designs with reference to the control circuit in the mid-cabinet during design test integrated circuit in the present embodiment according to the standard setting of mid-cabinet.
In the present embodiment, with reference to Fig. 2, the signal of the interface end function of power supply box with reference to table 1 is:
Table 1
The course of work of present embodiment is: when the VD4 switch normally uses; Aviation plug (female) is connected on aviation plug on the switch (male head) and the switch cubicle; Switch cubicle provides VD4 switch working power (comprise accumulation power supply, power supply unblocks), and switch cubicle is to the instruction of VD4 switch transmission divide-shut brake simultaneously.
During a VD4 switch maintenance test, this inspection switch disengaging respective switch cabinet breaks off aviation plug and connects, at this moment also parallelly connected other operating switch cubicle (and internal switch) on the switch cubicle; 1. this moment, this VD4 switch lost accumulation power supply, and maintenance needs artificial energy storage; 2. switch loses the power supply that unblocks, and closing locking can't close a floodgate, and need take the manual unlocking of switch panel apart;
The effect of switching characteristic experiment power supply case: 1, transform the female head of aviation plug, a contact that the reservation maintenance needs utilizes this female head to connect the male head on the VD4 switch, and some go out a little to be drawn out on the switching characteristic experiment power supply case with VD4 switch inside; 2, the built-in AC/DC changeover switch of switching characteristic experiment power supply case converts the 220V alternating current into direct current, and VD4 switch working power (comprise accumulation power supply, power supply unblocks) is provided; 3, switching characteristic experiment power supply case provides contact (the VD4 switch is passed in the divide-shut brake that sends high voltage switch tester instruction for (11) (12), (13) (14), and advantage is time saving and energy saving, safety.
Adopted present embodiment to carry out VD4 switching characteristic test, needn't remove the VD4 switch panel, also need not manually remove closing locking and manually energy storage certainly, can reduce workload, promote work efficiency and eliminate safe hidden trouble.
