Abstract
The utility model relates to a production and the use field of high -tension transmission equipment, concretely relates to condenser discharge specialized tool of transformer substation. Including insulator spindle, fixed mounting at the first contact of insulator spindle upper end, fixed mounting at the second contact in insulator spindle middle section, the fixed mounting ground wire plug at the insulator spindle lower extreme, first contact, second contact and ground wire plug pass through the wire establishes ties in proper order and is in the same place, and there is the pendulum rod in the middle section of insulator spindle through the hinge is articulated, and fixed mounting has the third contact on the pendulum rod, and the series connection has resistance between third contact and the second contact. This condenser discharge specialized tool can provide and discharge through the current -limiting of resistance, and also the accessible wire is direct discharges condenser ground connection, the guarantee work safety to the operating angle of action bars can be adjusted as required, convenient operation.
Description
Technical field
The utility model relates to production and the use field of high-voltage transmission equipment, is specifically related to a kind of substation capacitors electric discharge specific purpose tool.
Background technology
Shunt capacitor is as a kind of reactive-load compensation equipment, usually be connected on the low-voltage bus bar of transformer station, normal and on-load tap-changing transformer with the use of, for the reactive power of bucking-out system, improve power factor, thus reduce electric energy loss, raising quality of voltage and utilization rate of equipment and installations.As needs interruption maintenance is carried out to operating capacitor time, need discharge one by one to capacitor, if capacitor is placed in dielectric framework, also need to discharge to capacitor case.If direct copper conductor is to capacitor discharge, very large discharging current can be produced, be easy to damage the person or equipment.Chinese patent 2012100411550 discloses " a kind of discharging rod of capacitor ", hollow bar arranges a rotatable moving contact and one determine contact, and discharge resistance is set between, first can pass through conductive discharge, and then discharged by wire direct short-circuit, this two-stage electric discharge operation can guarantee safety of discharging, and improves the fail safe of work.But this discharging rod of capacitor is all arranged in the hollow bar as action bars due to two contacts, is arranged in a linear, and be inconvenient to adjust work angle, the scope of application is restricted.
Summary of the invention
The utility model is solve the problem to provide a kind of structure substation capacitors electric discharge specific purpose tool simple, safe and convenient to use, applied widely.
The technical scheme that the utility model adopts for technical solution problem is:
The ground wire plug that substation capacitors electric discharge specific purpose tool described in the utility model comprises insulating bar, is fixedly mounted on the first contact of insulating bar upper end, is fixedly mounted on second contact in insulating bar stage casing, is fixedly mounted on insulating bar lower end, described first contact, the second contact and ground wire plug are cascaded successively by wire, it is characterized in that: the stage casing of described insulating bar is hinged with fork by hinge, described fork is installed with the 3rd contact, between described 3rd contact and the second contact, is in series with resistance.
Described insulating bar and fork are pipe body, and described hinge is arranged in the inner chamber of pipe body, the sidewall of insulating bar are provided with the gap holding fork.
Owing to have employed said structure, this capacitor discharge specific purpose tool can be provided and be discharged by the current limliting of resistance, is also directly discharged by capacitor grounding by wire, safeguard work safety, and the operating angle of action bars can regulate as required, handled easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, the ground wire plug 4 that substation capacitors electric discharge specific purpose tool described in the utility model comprises insulating bar 1, is fixedly mounted on the first contact 2 of insulating bar 1 upper end, is fixedly mounted on second contact 3 in insulating bar 1 stage casing, is fixedly mounted on insulating bar 1 lower end, described first contact 2, second contact 3 and ground wire plug 4 are cascaded successively by wire, the stage casing of described insulating bar 1 is hinged with fork 6 by hinge 5, described fork 6 is installed with the 3rd contact 7, between described 3rd contact 7 and the second contact 3, is in series with resistance 8.For convenience of operation, as shown in Figure 1, bending can also be set in the stage casing of insulating bar 1, make its top and bottom knuckle at an angle.Certainly, as another embodiment of the present utility model, insulating bar 1 also can adopt the straight-bar not having knuckle.
Described insulating bar 1 and fork 6 are pipe body, and described hinge 5 is arranged in the inner chamber of pipe body, the sidewall of insulating bar 1 are provided with the gap 9 holding fork 6.Fork 6 is arranged in gap 9.
During use, ground wire plug 4 is connected ground wire, then touch the terminals electric discharge of capacitor successively with the 3rd contact 7, now capacitor is that discharging current is less by resistance 8 ground connection, fail safe is good; Touch the terminals electric discharge of capacitor subsequently again with the first contact 2 successively, now capacitor is by the direct ground connection of wire, can ensures to discharge residual charge as much as possible.As discharge effect need be confirmed further, the two poles of the earth of capacitor can also be touched with the first contact 2 and the second contact 3 simultaneously, its two poles of the earth short circuit is obtained equipotential.
