Abstract
The utility model provides a mutual inductor secondary wiring device. The inside of a guiding sleeve (1) is provided with a copper contact (5); the outside of the guiding sleeve (1) is provided with a centralizing block (3) which is pressed by a floating spring (2); and the copper contact is pressed by a retainer spring (4). The mutual inductor secondary wiring device realizes automation of mutual inductor secondary wiring, and realizes accurate and reliable mutual inductor secondary wiring.
Description
Technical field
The utility model relates to the full-automatic detection line of instrument transformer of electric power system, is specifically related to instrument transformer secondary connection device.
Background technology
Instrument transformer is the metrology devices of electric power system, and is very big to the workload of its detection.In order to save manpower, improve accuracy of detection and efficient, national grid is promoted the application of the full-automatic detection line of instrument transformer.When on transfer matic, detecting the parameter of instrument transformer, need with instrument transformer once, secondary coil and ground connection seat board be connected on the detecting instrument.Wherein, the difficulty of the automation wiring of secondary coil is bigger.
In order to realize the automation of instrument transformer secondary connection, and accurately and reliably, multiple connection plan is arranged at present.What have directly compresses the secondary coil terminal screw of instrument transformer with copper contact, because instrument transformer is crooked, can not guarantee both realization faces contacts, but the line contact, even the some contact; What have is installed in copper contact on the centering block, and servo-actuated centering angle compresses instrument transformer secondary connection screw, because the site error of instrument transformer can not guarantee enough contacts area, thereby contact resistance is exceeded standard.
Summary of the invention
The purpose of the utility model provides a kind of instrument transformer secondary connection device, with the automation of realization instrument transformer secondary connection, and accurately and reliably.
The purpose of the utility model realizes through following measure, a kind of instrument transformer secondary connection device, and copper contact 5 is equipped with in its fairlead 1 inside, and wiper block 3 is equipped with in the outside of fairlead 1.Floating spring 2 is being pressed wiper block; Holddown spring 4 is being pressed copper contact.
There is the guiding surface 9 of symmetry above-mentioned wiper block 3 belows, and wiper block 3 belows also have the plane 8 that adapts with instrument transformer end face size.
The utlity model has three characteristics: the one, this device has wiper block 3.Wiper block 3 fluctuates along two fairleads 1, and under the effect of floating spring, wiper block applies suitable pressure to instrument transformer.Realized setting upright earlier compressing again, made instrument transformer upright and stable, last copper contact compresses terminal screw, implements reliable wiring.The 2nd, there are two guiding surfaces wiper block 3 belows, also have the plane that adapts with instrument transformer end face size.Along with moving down of whole device, the guiding surface of wiper block at first touches the instrument transformer arris of angled top within the specific limits, under the guide effect on inclined-plane, the instrument transformer of inclination is set upright.Whole device continues to move down, and the plane of wiper block contacts and compresses with the end face of instrument transformer, makes it stable.Then, copper contact touches the secondary connection screw of instrument transformer, and both align, and guarantees that the contact area of two end faces is enough big.Holddown spring 4 guarantees enough pressure 4Kgf, thereby guarantees that contact resistance does not exceed standard.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
Embodiment 1: see figures.1.and.2, copper contact 5 is equipped with in fairlead 1 inside, and wiper block 3 is equipped with in the outside of fairlead 1.Floating spring 2 is being pressed wiper block; Holddown spring 4 is being pressed copper contact 5.
There is the guiding surface 9 of two symmetries the below of wiper block 3, and wiper block 3 has the plane 8 that adapts with instrument transformer 7 end face sizes.Whole device moves down near instrument transformer under the effect of cylinder, and the guiding surface of wiper block at first touches the instrument transformer arris of angled top within the specific limits, under the guide effect on inclined-plane, the instrument transformer of inclination is set upright.Whole device continues to move down, and the plane of wiper block contacts with the end face of instrument transformer, and under the effect of floating spring, compresses instrument transformer, makes it stable.Then, copper contact touches the secondary connection screw 6 of instrument transformer, and both align, and guarantees that the contact area of two end faces is enough big.Holddown spring 4 acts on the copper contact 5, guarantees enough pressure 4Kgf, thereby guarantees that contact resistance does not exceed standard.
Claims (2)
