Description

Quick switching device for Zero flux CT secondary electron module test wiring
Technical field
The invention belongs to power equipments to test field, more particularly to a kind of for zero-flux current transformer CT secondary electron The quick switching device of module test wiring.
Background technique
Zero-flux current transformer CT is used widely in DC converter station, such as:Input quantity is 3000A direct current Zero flux CT when to the secondary electron module test of such CT, needs to measure 24 data when most, and one data of every measurement When will change the mode of connection, be all the method wave in this way to such equipment test in converter station domestic at present Take the plenty of time, while frequently disconnecting line on the connecting terminal by testing equipment and be easy to causeing equipment damage, therefore we need Want a kind of quick switching device suitable for Zero flux CT secondary electron module test wiring.
Summary of the invention
In order to overcome the deficiencies of the prior art, the object of the present invention is to provide one kind tries for Zero flux CT secondary electron module The quick switching device of wiring is tested, structure is simple, and it is easy to operate, simplify the module test wiring of Zero flux CT secondary electron, is not easy Damage is by testing equipment.
To achieve the above object, the invention is realized by the following technical scheme:
For the quick switching device of Zero flux CT secondary electron module test wiring, Zero flux CT secondary electron mould is realized It carries out plug between block and testing equipment to dock, including taken amount terminal, selection switch, secondary electron module end plug, measuring device Plug, test wire are held, taken amount terminal one end is connect by test wire with secondary electron module end plug, and the other end and selection switch Connection, measuring device end plug are connect by test wire with selection switch end of incoming cables.
The taken amount terminal is several, is respectively connected with simulated failure connecting terminal on each taken amount terminal.
The application method of quick switching device for Zero flux CT secondary electron module test wiring, secondary electron module End plug is docked with the Zero flux CT secondary electron module connecting terminal tested, and measuring device end plug and measuring device connect Line end connection, the signal for each terminal of Zero flux CT secondary electron module connecting terminal tested are picked up onto taken amount terminal, Pull the i.e. convertible different modes of connection of selection switch, data needed for measuring;It is connect by the simulated failure on connection taken amount terminal Line terminals simulate unusual service condition, measure abnormal data.
Compared with prior art, the beneficial effects of the invention are as follows:
Overcome that previous Zero flux CT secondary electron module test wiring is complicated, time-consuming, the defect of equipment easy to damage.It is real Zero flux CT secondary electron module is showed to dock with progress plug between testing equipment, avoid anti-on the terminals by testing equipment Line is disconnected again, need not power off when measuring different parameters, change wiring, and institute can be measured by only needing the selection on trip gear to switch Need parameter.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure:1- taken amount terminal 2- selects switch 3- secondary electron module end plug 4- measuring device end plug 5- mould Quasi- mistake wiring terminal.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that implementation of the invention is unlimited In the following embodiments and the accompanying drawings.
See Fig. 1, for the quick switching device of Zero flux CT secondary electron module test wiring, realizes Zero flux CT bis- times Between electronic module and testing equipment carry out plug dock, including taken amount terminal 1, selection switch 2, secondary electron module end plug 3, Measuring device end plug 4, simulated failure connecting terminal 5,1 one end of taken amount terminal by secondary electron module end plug 3 with it is secondary Electronic module connection, the other end are connect with selection switch 2, and measuring device end plug 4 passes through measuring device end plug 4 and measuring instrument Device connection;Taken amount terminal 1 is several, is respectively connected with simulated failure connecting terminal 5 on each taken amount terminal 1.
The plug of secondary electron module end plug 3 is in strict accordance with Zero flux CT secondary electron module binding post size system Make, may be implemented well to dock, after docking, the signal of each terminal of Zero flux CT secondary electron module connecting terminal passes through secondary electricity Submodule end plug 3 is picked up onto taken amount terminal 1, is selected switch 2 to realize and is connected to make to measure from different taken amount terminals 1 Equipment measures required data.By connection taken amount terminal 1 on simulated failure connecting terminal 5, can with analog power failure, connect A variety of unusual service conditions such as ground, electronic device failure measure abnormal data, the whether correct output signal of verifying attachment.
The application method of quick switching device for Zero flux CT secondary electron module test wiring, secondary electron module End plug 3 is docked with the Zero flux CT secondary electron module connecting terminal tested, measuring device end plug 4 and measuring device Terminals connection, the signal for each terminal of Zero flux CT secondary electron module connecting terminal tested are picked up to taken amount terminal 1 On, pull the i.e. convertible different modes of connection of selection switch 2, data needed for measuring.
That the present invention overcomes previous Zero flux CT secondary electron module test wiring is complicated, time-consuming, equipment easy to damage Defect.It realizes Zero flux CT secondary electron module to dock with progress plug between testing equipment, avoid in connecing by testing equipment Line is disconnected on line end repeatedly, need not be powered off when measuring different parameters, change wiring, the selection on trip gear is only needed to switch i.e. Required parameter can be measured.
