At electric field, due to the demand of people to intelligent instrument, high efficiency working method, and the demand of safe operation, ancient and the simple mode of connection also needs to change.Fig. 1 is widely used and ancient a kind of binding post in the market.Current transformer 1 enters binding post 5 through wire 2, and then enters measuring instrument 3 by wire.According to the wiring standard requirement of national regulator cubicle, secondary connection must enter secondary meter again through intermediate connection terminal.According to the characteristic requirements of current transformer, current transformer is when to be measured while once having electric current, and secondary does not allow open circuit, and open circuit can burn instrument transformer.In the time carrying out measuring instrument maintenance and change, the wiring of instrument need to be removed so, the mode of Field Force's quick and safe is exactly to insert the different short circuit wire of a Gent at 2 wiring holes so, prepare in advance this root wire.
Current existing technical scheme is a kind of more ancient scheme, has a lot of shortcomings: (1) will prepare special wire.When short circuit, special wire is inserted to wire wiring hole.(2) operating efficiency is lower.Before safeguarding, to find and prepare wire, then carry out short circuit to scene.(3) there is safety in operation.In the time carrying out short circuit, insert with hand, in the time that wire carries out naked copper, can bring potential safety hazard to the person.(4) integrated short circuit eliminate misplug, misplug and leakage insert, and ensures safety utilization of electric power and safety in production.
Summary of the invention
For this intermediate connection terminal, in the time that instrument is changed and keep in repair, the utility model need to be by any jointer and pilot wire, utilizes terminal self structure to realize short circuit.And this terminal is indicated short circuit and off-state instruction in addition.The utility model solves aim: exempt from wire and connect, exempt from screwdriver, the potential safety hazard while eliminating hot line job.
The utility model proposes a kind of current transformer short circuit integrated terminal, it comprises: left side cover 1, right side cover 2, pair of terminal conductive copper bar 3, turnover wire wiring fixed engagement copper bar 4, pair of conductive copper bar short circuit engagement copper bar 5, fixing access wire screw 6, insulation drives short circuit copper bar swing handle 7 and the short circuit status indicator board 8 with Dan Suo mechanism, wherein, fixing access wire screw 6 is fixed on turnover wire wiring fixed engagement copper bar 4, and penetrates the terminal conductive copper bar 3 in left side and the terminal conductive copper bar 3 on right side; Then respectively the terminal conductive copper bar 3 on the terminal conductive copper bar 3 in left side and right side is fitted into left side cover 1 and right side cover 2; Insulation drives short circuit copper bar swing handle 7 to be fixed on the conductive copper bar short circuit engagement copper bar 5 on left side and right side, then insulation is driven to the combination of short circuit copper bar swing handle 7 and conductive copper bar short circuit engagement copper bar 5 cover 1 on the left of being fitted into together with short circuit status indicator board 8 with Dan Suo mechanism; Finally again left side cover 1 and right side cover 2 are assembled together.

Embodiment
Also with best embodiment, the utility model is described in detail below in conjunction with accompanying drawing.
The utility model terminal is by following important component part: left side cover 1; Right side cover 2; Pair of terminal conductive copper bar 3; Turnover wire wiring fixed engagement copper bar 4; Pair of conductive copper bar short circuit engagement copper bar 5; Fixing access wire screw 6; Insulation drives short circuit copper bar swing handle 7; With the short circuit status indicator board 8 of Dan Suo mechanism.Fixing access wire screw 6 is fixed on turnover wire wiring fixed engagement copper bar 4, and penetrates the terminal conductive copper bar 3 in left side and the terminal conductive copper bar 3 on right side; Then respectively the terminal conductive copper bar 3 on the terminal conductive copper bar 3 in left side and right side is fitted into left side cover 1 and right side cover 2; Insulation drives short circuit copper bar swing handle 7 to be fixed on the conductive copper bar short circuit engagement copper bar 5 on left side and right side, then insulation is driven to the combination of short circuit copper bar swing handle 7 and conductive copper bar short circuit engagement copper bar 5 cover 1 on the left of being fitted into together with short circuit status indicator board 8 with Dan Suo mechanism; Finally again left side cover 1 and right side cover 2 are assembled together to composition the utility model.
We know that one-shot measurement current transformer is the alternating current instrument transformer of measuring large electric current, and the electric current of output is also entered and outputed to terminal by 2 wires at several amperes, then enters instrument and measures.So a current transformer must enter instrument again through the terminal connections of two.In Fig. 2, the utility model directly does two terminals together, and realizes the current terminal of exempting from instrument short circuit by inner complicated structure.
On-the-spot application staff execution mode, in the time of needs short circuit, the swing handle 7 in field personnel's rotation diagram 3 upwards spin-up, and drive short circuit engagement copper bar 5 also to move upward, and terminal conductive copper bar 3 carries out fastening engagement.At this moment short circuit sign board 8 is from shrinking and move upward along with the movement of rotary handle makes to play shrinking structure in housing, and demonstrates at present in short circuit process, and in the time being rotated in place, whole Sign Board also reveals, and mark short circuit completes.After site operation personnel fixes a breakdown, rotation swing handle 7 is rotated down, and Sign Board 8 Dan Suo mechanisms carry out resilience and move downward.After in Sign Board is submerged in housing, swing handle also cannot move down, and at this moment conductive copper bar short circuit engagement copper bar 5 separates with the mating surface of terminal conductive copper bar 3, has both reached the object of disconnection.
Because terminal loaded current transient current reaches 30 ampere left and right, usually be operated in 5A left and right, require so conductive copper bar short circuit engagement copper bar 5 and the 3 surface engagements of terminal conductive copper bar rigorous and fastening, the utility model has carried out oxidation processes to the surface of conductive copper bar short circuit engagement copper bar 5 and terminal conductive copper bar 3 so, and the mating surface that carries out taper reaches higher engagement degree.
The utility model advanced technology, the demand of applicable intelligent electric application market, brings very large Social benefit and economic benefit.Benefit following points: (1) has improved operating efficiency, fixes a breakdown in time.In the time that scene needs short circuit, do not need to find special short circuit wire, do not need screwdriver tool, only within 10 seconds, short circuit completes.
(2) reduced cost.Although this terminal with respect to the relative raising 40% of the terminal price in existing program, is used the more expensive special short circuit wire (wire is removable, may cause loss) of this price of purchase repeatedly so.The cost causing is higher.
(3) eliminate personal safety hidden danger.Due to the scheme of applying in the market, all need manually to carry out the plug of shorting stub, hot line job is carried out in screwdriver rotation, brings personal safety to these operating personnel.
(4) eliminate Electrical Safety accident, ensure safety in production.In existing program, while carrying out wire short circuit, easily because causing misplug and leak, manual operation inserts.Cause primary current instrument transformer to burn, the replacing that will have a power failure, brings production heavy losses.
Above embodiment is the more preferably one of embodiment of the utility model, and the common variation that those skilled in the art carry out within the scope of the technical program and replacement should be included in protection range of the present utility model.
