Other examples can have different values.It should also be noted that similar label and letter indicate similar terms in following attached drawing,
Therefore, it once being defined in a certain Xiang Yi attached drawing, then in subsequent attached drawing does not need that it is further discussed.
As shown in attached drawing 1-4, the present invention provides a kind of test wire jointer with voltage monitored and assist storage function,
It includes insulating bi-layer mounting box 1, the hinged shaft 2 for being vertically arranged in 1 middle part of the insulating bi-layer mounting box, is connected by hinged shaft 2
And the left insulating clip body 3 for being insulated 1 lower layer of box and right insulating clip body 4, setting are set in the fixed setting insulation
The monitoring arrangement with voltage on double-deck 1 upper layer of mounting box and the auxiliary being equipped with the monitoring arrangement with voltage storage fill
It sets, the auxiliary storage device includes the flexible insulated hose band 10 that 3 tail end of left insulating clip body is arranged in, the earth lead 9
It is set in flexible insulated hose band 10, on the one hand forms the protection to earth lead 9, avoid leading to its abrasion leakage due to misoperation
Electricity causes harm to the human body after on the other hand can also preventing 9 breakage of earth lead.
The monitoring arrangement with voltage includes being fixed at 1 top of insulating bi-layer mounting box and being located at hinged shaft front end
Contact pilotage 5, be fixedly connected with 5 tail end of contact pilotage test line interface 6, with the voltage sense that is fixedly connected in the middle part of the contact pilotage 5
Answer indicator light 7 and with the voltage induced indicator light 7 by the concatenated earth lead 9 of resistance 8, the present invention is without opening direct current
Test wire can be directly connected in DC terminal row, improve work efficiency, while also increasing by original wiring of terminal block
Safety, has very great help to the experiment work of substation secondary profession.
The front end of the left insulating clip body 3 and right insulating clip body 4 is connected by tension spring 13, and torsional spring is arranged on the hinged shaft 2
16, guarantee that left insulating clip body 3 is mutually closed with the front end of right insulating clip body 4 and belong to normality situation, the left insulating clip body 3 and the right side are exhausted
Lantern ring 12 is arranged in the tail end of edge clamp 4, and when needed, operator protrudes into hand in lantern ring 12, rotates backward left insulating clip body 3
With right insulating clip body 4, separate its left insulating clip body 3 and 4 front end of right insulating clip body.
The present invention it is normal be not used when in a not used clip shape, in use, test wire is inserted into this hair
In bright test wire access aperture, then, clip is opened, is clipped on DC terminal row, this is, intermediate contact pilotage can just push up
Firmly on two screws of DC terminal row, to realize the imagination on test wire " insertion " DC terminal row.Due to contact pilotage 5
With certain stretching elasticity, when clip is clipped in terminal block, contact pilotage 5 is to shrink to withstand on terminal block screw, this just increases
The reliability of contact is added, while being also beneficial to clip and being fixed in terminal block.The collet and folder tail of clip are all isolation materials,
It avoids and accidentally touches the situation that terminal block causes short circuit.
Assuming that the voltage circuit in certain interval secondary circuit is connected on DC terminal row, we will be to the relay protection at this interval
Device carries out all schools.So, after being connected to the secondary line of mutual inductor side on opening terminal block and carry out insulation measures, it would be desirable to
Test wire is inserted into terminal block, test voltage is added to protective relaying device.At this moment, test wire is linked into the present invention, and
The present invention, which is clipped on DC terminal row, can be realized.After connecting, we can open the ground line rolled at folder tail, will be grounded
Ground row where line touches protective device in screen cabinet, i.e. contact ground potential, see whether voltage monitoring lamp is lighted, and monitoring lamp does not work,
Illustrate that former working voltage is isolated in this terminal block, after test voltage is added with tester, monitoring lamp is lighted, and illustrates to test
Voltage has been added, and forbids accidentally touching.
The contact pilotage 5 is internally provided with pressure spring 14, and the pressure spring 14 is located between the front end and middle part of contact pilotage 5, the pressure
Movable end is arranged in the front end of spring 14, and fixing end is arranged in middle part, and for the pressure spring 14 between movable end and fixing end, contact pilotage 5 is living
Moved end, which is withstood, can spring back certain amplitude after thing, therefore there is certain pressure in when 5 movable end of contact pilotage withstands thing, guarantees to connect
Touching is reliable.
The contact pilotage 5 is two, contact pilotage 5 it is corresponding with the voltage induced indicator light 7 being fixedly connected in the middle part of the contact pilotage 5 with
And passing through the concatenated earth lead 9 of resistance 8 with the voltage induced indicator light 7 is two sets, it is a set of wherein to occur contacting not
When good or other problems, another covering device can play the role of prevention insurance, improve the security performance of device.
Collet 15 is respectively set in the front end of the left insulating clip body 3 and right insulating clip body 4, and 15 contact surface of collet is saw
Tooth form guarantees clamping fastness, and avoiding clamping from loosening causes testing result occur to be not allowed security risk occur.
The insulating bi-layer mounting box 1, left insulating clip body 3 and right insulating clip body 4 are glass reinforced plastic epoxide resin material, dress
The metal conduction portions set all are wrapped in insulating materials, ensure that safe handling effect.
Velcro bandage 11 is fixedly installed on the flexible insulated hose band 10, can be convenient and bind earth lead 9, side
Just arrangement storage is carried out to earth lead 9.
Working principle is as follows:
The present invention is integrally in the shape of a clip, and main body uses isolation material, but is fixed with two in the two sides of clip axis
The contact pilotage 5 of a test wire contact shape, contact pilotage 5 be directed toward clamp aperture direction, metal material, built-in spring, withstand thing with
After can spring back certain amplitude, therefore, there is certain pressure in when contact pilotage 5 withstands thing, guarantees that contact is reliable.The tail portion of contact pilotage 5 is
Line interface 6 is tested, the insertion of electrical secondary system common test line is suitble to.Two contact pilotages, one voltage induced indicator light 7 of each correspondence, voltage
Induction 7 one end of indicator light is connected with contact pilotage 5, and 7 other end of voltage induced indicator light is connected with one section of longer earth lead 9, voltage
The induction string of indicator light 7 has very big resistance 8, and after contact pilotage 5 is touched terminal block screw, earth lead 9 is contacted ground potential,
It whether can show in terminal block with voltage.If there is electricity, then indicator light is bright, does not have, then indicator light does not work.In this way, can be with
It monitors and whether has voltage in terminal block, improve work safety.The earth lead 9 of voltage induced indicator light 7 is along left insulating clip body 3
Tail portion side stretch out, be through tail portion connection the flexible insulated hose band 10 with Velcro bandage 11, only end exposing one
Head facilitates contact ground potential, and flexible insulated hose band 10 can be being rolled up when not in use as clip tail portion side, need using when beat
It opens.
