Description
Technical field
The utility model belongs to power equipment test field, particularly relates to a kind of zero-flux current transformer test rapid wiring device.
Background technology
At present, in DC converter station, zero-flux current transformer CT is used widely, primary equipment as CT needs to connect 3000A direct current, and the secondary electron module of CT needs 110V DC supply, during primary equipment and secondary electron module test therefore to this type of CT, heavy is needed to be transported to direct current cabinet room by testing equipment, direct supply is got from direct current cabinet, get AC power from AC socket again simultaneously, test connection is complicated, on-the-spot chaotic, the change mode of connection expends time in, easy wrong line or the personnel that cause get an electric shock, more seriously this type of CT equipment price is expensive, easily device damage is caused to repeatedly being disconnected line by the connection terminal of testing equipment, therefore one is needed not limit by place, the Zero flux CT test unit of easy-to-connect.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of zero-flux current transformer test rapid wiring device, and structure is simple, easy to operate, and Zero flux CT is tested and does not limit by place, test connection facilitates, and not fragilely testedly tests equipment.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of zero-flux current transformer test rapid wiring device, comprise power transfer module, DC current generation module, mode of connection modular converter, direct supply output plug, DC current lead-in wire, test wire, power transfer module is connected with DC current generation module, power transfer module is connected with direct supply output plug, ac power plug, DC current generation model calling has DC current to go between; Test wire one end is provided with primary equipment end plug, and the other end is provided with secondary electron module end plug; Mode of connection modular converter is provided with switch, and mode of connection modular converter input end is connected with surveying instrument connection plug, and output terminal is connected with Zero flux CT secondary electron module connection plug.
Described power transfer module is WYK series DC current regulator power supply.
Compared with prior art, the beneficial effects of the utility model are:
Structure is simple, easy to operate, and Zero flux CT is tested and does not limit by place, test connection is convenient, not fragilely testedly tests equipment, overcomes the shortcoming that Zero flux CT test connection complexity, length consuming time, the place that is put to the test in the past limit.
Achieve and complete the primary equipment of Zero flux CT and the experiment work of secondary electron module in same place, need not find the place of direct supply again, Zhi Qu mono-tunnel AC power both can meet test demand; Test plug can realize and be tested appliance terminal and dock, and avoids repeatedly tearing pair of connecting wires equipment open and causes damage; Mode of connection modular converter can realize being connected with by plug between testing equipment and test apparatus, when measuring different parameters need not power-off, change wiring, only the switch need pulled in module can measure desired parameters.Overcome the shortcoming of Zero flux CT test connection complexity, length consuming time, the place restriction that is put to the test in the past.
