Description
Technical field
The utility model relates to a kind of connection terminal of measuring current, current terminal splicer used when particularly a kind of secondary side to operating current transformer is tested.
Background technology
Current transformer is a kind of important power equipment, is widely used in electric system.The secondary side that the electromagnetic principle of current transformer determines it forbids open running, the secondary side of current transformer is once open circuit, thousands of volt can be produced on the secondary circuit of working voltage originally only having millivolt level, the high voltage of even tens thousand of volt, not only badly influence the normal operation of secondary loop of mutual inductor, also can cause the electric discharge of open circuit point, initiation fire and the accident of burning electrical equipment, the high pressure that even secondary side produces also directly can jeopardize the life security of staff.And the work such as power equipment starting characteristics test and operational outfit parameter testing must be carry out under power equipment operating condition.When carrying out starting characteristics test or operational outfit parameter testing, as the secondary operating loop of the current transformer of measurement power equipment most important parameters, must be cascaded by test wire and test apparatus, just can carry out related tests.At present, the conveniently connection of test lead, and prevent the open circuit of Current Transformer Secondary side, be generally adopt following measures: be furnished with jack in the both sides of mutual inductor secondary side current loop terminals, centre is provided with removable sheet; Test wire two is provided with plug.During experiment, one end plug of test wire is inserted in current transformer terminal jack, the other end of test wire is inserted in the current transformer terminal jack of test instrument, disconnect the removable sheet in mutual inductor secondary side current loop current terminal, just secondary loop of mutual inductor can be concatenated in test instrument.This connected mode, because be adopt the mode of plug-socket to carry out connecting, in an experiment when nigration instrument or operating personnel touch test wire by mistake, be easy to the phenomenon that generation test wire plug is drawn out from current transformer terminal jack, cause Current Transformer Secondary side to be opened a way, and open circuit point electric discharge occurs burn electrical equipment and jeopardize the accident of personal safety.
Summary of the invention
The utility model provides a kind of current terminal splicer, solves the test wire when doing operation power equipment test and easily to come off the technical matters causing Current Transformer Secondary side to be opened a way.
The utility model solves above technical matters by the following technical programs:
A kind of current terminal splicer, comprise connecting line receptacle body and wiring circle body, one end of brace and the bottom of connecting line receptacle body are fixed together, the other end and the wiring circle body of brace are fixed together, in the wiring circle body fixed orifice of wiring circle body, activity cross-under has coupling bolt, the sidewall of connecting line receptacle body is provided with top wire hole, jackscrew is provided with in top wire hole, on brace and on the lateral surface of connecting line receptacle body, be provided with insulation sleeve housing, insulation sleeve housing is provided with jackscrew rotating hole.
Coupling bolt below wiring circle body fixed orifice is provided with anticreep fin; Brace is inclined upwardly 45 degree of settings.
The utility model solves the difficult problem that when operation power equipment is tested, test wire comes off, and greatly reduces the potential safety hazard of open circuit of secondary loop of current transformer during test, and execute-in-place is simple, reliably easy to loading and unloading.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
