Technical field
The utility model relates to a kind of wire clamp troubleshooting instrument, particularly a kind of wire clamp heating tape electric treatment instrument.
Background technology
Along with power load increases, difficulty and pressure that equipment has a power failure are increasing, and equipment component is transformed, safeguards untimely, causes disconnecting link wire clamp heating accident in rising trend, particularly in the transformer station that some running environment are relatively more abominable, equipment is old, load is heavy, problem is particularly outstanding.In operation of power networks, be that a wire clamp heating accident carries out equipment and have a power failure to process more difficultly, need a series of formality, yet do not process, there is the potential safety hazard of operation of power networks.At present still only can rely on the power failure mode heating position of device clamp is processed, this not only affects Substation Electric Equipment Operation safety and reliability, brings common economic loss also for simultaneously user and power supply enterprise.In addition, the instrument of have a power failure processing is heavier, operates more loaded down with trivial detailsly, and operating personnel's intensity is larger.
The utility model content
The purpose of this utility model be according to the deficiencies in the prior art part provide a kind of can be with the wire clamp heating tape electric treatment instrument of electric treatment disconnecting link heating wire clamp.
The purpose of this utility model realizes by following approach:
Wire clamp heating tape electric treatment instrument, its structural feature is, the steelframe, conductive clip, conductive connecting and the bolt that include a side opening are carried out member, wherein steelframe is comprised of upper crossbearer, vertical rack and lower cross frame, conductive clip includes upper clip and lower clamping piece, and a side end of lower clamping piece is connected with vertical rack, and the downside of lower clamping piece is fixedly connected with lower cross frame simultaneously, one side end of upper clip is C type structure, and this C type structure can be placed around vertical rack periphery edge; Be provided with internal thread through hole on upper crossbearer, bolt is carried out member and is connected with this internal thread through hole, and passes this internal thread through hole the one end is fixedly connected with upper clip; The both ends of conductive connecting connect respectively upper clip and lower clamping piece.
In described charged handling implement, upper clip in conductive clip is moved up and down take vertical rack as guide rail by the end of its C type structure, lower clamping piece is fixed on the lower cross frame of steelframe, carry out member by operating screw, under the control of internal thread through hole on upper crossbearer, promote upper clip close to lower clamping piece, realize clamping.In operation, conductive clip is clamped the heating wire clamp, carry out member by the insulated operating rod operating screw, promote upper clip and clamp, thereby realize hot line job.
The utility model designs according to following analysis principle:
At first the wire clamp heating cause is analyzed, is mainly contained the following aspects:
(1) wire clamp contact: this is the main factor that guarantees low contact resistance.But wire clamp is through after long-time running, and the factor impacts such as bolt gets rusty, expands with heat and contract with cold, operational shock may the disconnecting link bolt looseness, and the wire clamp contact reduces.
(2) load current: along with the acceleration of economic construction, power consumption sharp increase, critical, fully loaded even overload operation that the electric equipment of part transformer station is in.Therefore, superheating phenomenon easily appears in device clamp.
(3) loose contact: have a plurality of factors to cause loose contact by wire clamp, comprise evenness, metal oxide layer of environmental pollution, galvano-cautery, contact-making surface etc.
In addition, wire clamp heating is also relevant with wire clamp material, contact area.
According to theoretical analysis and calculation: wire clamp contact-making surface resistance is R, and the power that consumes during by contact-making surface when electric current I is: P=I
2R；
P is exactly the energy source that makes conductor joint heating, if there is no heat radiation, and P will make the temperature of joint constantly raise, but in fact, heat radiation and heating are simultaneous, do not rise so temperature rise △ T is not straight line, rise but be exponential curve, reach stable through after certain hour.What we were concerned about is not the temperature rise process of heating, but stablizes later temperature rise value △ T.
△ T=PRr, in formula, P---hot-fluid, i.e. thermal power;
The thermal resistance of Rr---joint, unit K/W; Temperature rise reach stable after, the power that electric current I produces by contact-making surface
It is hot-fluid.
△ T=I
2The stable temperature rise value that RRr causes when representing by every watt of hot-fluid.It means what of conduction, convection current, 3 kinds of outside distribute heats of form of radiation by.If it is faster to dispel the heat, the stable temperature rise △ T that causes by identical hot-fluid P is just less, and namely thermal resistance is less; Vice versa.Hence one can see that, and the condition that affects the connector temperature temperature rise has three: the resistance R of joint itself, what thermal resistance Rr of load current I and expression heat radiation.R is must condition in three conditions.When R was very little, even by larger electric current I, joint can not generate heat yet, so R has the necessary condition that certain numerical value is conductor joint heating.In analysis below, be certain for the wire clamp thermal resistance of installation and operation.
Contact resistance R is mainly by decisions such as wire clamp material, contact area, contact, contact-making surface situations, for the wire clamp that has moved, wire clamp material, contact area, contact-making surface situation must in the equipment reprocessing that has a power failure, therefore only have from increasing contact and start with.
And the load current aspect, if can increase drainage channel in wire clamp, the load current that reduces to flow through wire clamp just can be alleviated the wire clamp the degree of heat.Therefore, solve heating defect in charged situation, tool design is from increasing the wire clamp contact and reducing two aspects of load current.
The utility model clamps wire clamp by conductive clip, thereby increase the wire clamp contact, conductive connecting is fixed between upper clip and lower clamping piece, make upper clip and lower clamping piece form a flow-guiding channel, split channel is: terminal block under disconnecting link top wire clamp-upper clip-conductive connecting-lower clamping piece-disconnecting link, reduce to be flowed directly to from the top wire clamp electric current of lower terminal block, realize the shunting action to the heating wire clamp.Described instrument volume is little, lightweight, the operation light and flexible, can alleviate operating personnel's labour intensity.
The utility model can further be specially:
