The cable device has the advantage of reasonable design, simple operation, quickness, accuracy, safety, reliability, etc.; moreover, the test of the switching property of the trolley is realized through the test socket and the test plug connected with the on-off plug of the trolley and the secondary socket of the switch cabinet.
Description
Technical field
The utility model belongs to the vacuum circuit breaker field, especially a kind of cable installation that is used to test the car switch characteristic.
Background technology
In the Operation of Electric Systems process, often need to use car switch that the circuit of electric system is carried out switching and failure removal, and the characteristic of car switch is the assurance of fault excision accuracy.In order to guarantee the characteristic of car switch, need regularly the characteristic of car switch to be tested at power supply unit.The characteristic test method of existing car switch generally will unload the front panel of car switch, the manually locking of unlocking electromagnet, the combined floodgate lead-out terminal and the separating brake lead-out terminal that connect corresponding lead-in wire and be linked into test instrument respectively carry out closing operation and sub-switching operation, if also need to carry out manual stored energy operation when energy storage not.Above-mentioned method of testing exists wiring confusion, complicated operation, test duration than problems such as length, in the wiring process, is easy to take place electric shock and waits mishap simultaneously, has certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design, cable installation that is used to test the car switch characteristic that test operation is simple, quick and safe and reliable is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of cable installation that is used to test the car switch characteristic, comprise test jack and test plug, closing locking circuit, accumulation power supply in test jack and the test plug link together by cable, closing circuit, sub-gate circuit in the test jack are connected with tester by p-wire, and test jack is connected with the switch cubicle Secondary socket with the car switch plug respectively with test plug.
And described car switch is the 10KV car switch.
And described test plug is 58 a pins control plug, and described test jack is 58 a holes control socket.
Advantage of the present utility model and good effect are:
1, this cable installation has test jack that is connected with the car switch plug and the test plug that is connected with the switch cubicle Secondary socket, in use, only need the car switch plug is pulled up from the switch cubicle Secondary socket, test jack and test plug are inserted into respectively on car switch plug and the switch cubicle Secondary socket, p-wire is connected on the tester can carries out the test of dolly characteristic, directly operate and just can finish separating brake at tester, test such as the test of closing a floodgate, have simple to operate, characteristics fast and accurately.
2, this cable installation is connected with the switch cubicle Secondary socket with the car switch plug with test plug by test jack, and the potential safety hazard of having avoided direct lead-in wire to bring has been avoided the generation of mishap, has safe and reliable characteristics.
3, the utility model is reasonable in design, is connected with the switch cubicle Secondary socket by test jack and test plug and car switch plug and has realized characteristic test to car switch, have simple to operate, quick and precisely, characteristics such as safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a test connection diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of cable installation that is used to test the car switch characteristic, as shown in Figure 1, by test plug 1, test jack 2, cable 3 and p-wire 4 connect and compose, this test plug is 58 a pins control plug, this test jack is 58 a holes control socket, closing locking circuit and accumulation power supply in test plug and the test jack link together by cable, test jack is used for being connected with the car switch plug, test plug is used for being connected with the switch cubicle Secondary socket, closing circuit in the test jack, sub-gate circuit is drawn by p-wire, and this p-wire is used for being connected with tester.
VD4 type 10KV car switch with ABB is that example describes below, 4 of this car switch plug, 14 pins are closing circuit, 30,31 pins are sub-gate circuit, 20,49 pins are closing locking circuit, 25,35 pins are accumulation power supply, therefore, with 20 in test jack and the test plug, 49,25,35 carry out interconnected, the closing locking circuit and the accumulation power supply that are about in test jack and the test plug are interconnected, and with 4 in the car switch plug, 14,30,31 pins are drawn with p-wire, are about to the interior closing circuit of test jack and test plug and are connected with p-wire with sub-gate circuit.
The connection of the utility model when test as shown in Figure 2, at first the car switch plug is pulled up from the switch cubicle Secondary socket, then test jack and test plug are inserted into respectively on car switch plug and the switch cubicle Secondary socket, the p-wire of test jack is connected on the tester, at last, directly just can finish tests such as separating brake, combined floodgate test, realize characteristic test car switch in the tester operation.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
