Abstract
The utility model discloses an oil supplementation tool for a mutual inductor. The oil supplementation tool comprises a hollow shell, wherein the inner wall of the shell is of the step shape; the shell is provided with an exhaust valve and an oil supplementation nozzle that are communicated with the inner wall of the shell; one end of the shell is provided with internal screw thread; a switching mechanism penetrates through the shell and stretches out of the shell; the switching mechanism corresponding to the oil supplementation nozzle and the exhaust nozzle is provided with an exhaust or oil-supplementation switching port; and the other end of the shell is sealed with the switching mechanism by a sealing ring. The oil supplementation tool has the following advantages that the oil supplementation for the mutual inductor can be realized conveniently and fast; the process of oil supplementation can be safe and reliable; and the technical characteristic of insulating oil and the operation safety of equipment can be ensured. The oil supplementation tool can solve the technical problems that the maintainer can not realize the oil supplementation maintenance for the equipment on the spot safely, fast and conveniently as the oil level of the mutual inductor is low, and the mutual inductor meets the requirement of safe operation, thereby laying the foundation for the safe operation of the equipment.
Description
Technical field
The utility model relates to a kind of repairing instrument, relates to a kind of repairing instrument that is applied on the instrument transformer specifically.
Background technology
LCWB6-110W1 current transformer, JDCF-110W voltage transformer are that porcelain is box, the hermetically sealed insulation system of capacitor type, metal expander is equipped with at the top, the fuel head indicating dial is arranged on the expander, can observe fuel head easily by the expander outer cover, therefore 110kV transformer station generally uses under company.And regulation " generally speaking, must not destroy the sealing state of product easily, the test of also not drawing oil sample easily is lower than normal oil level after drawing oil sample, and should mend qualified transformer oil immediately " in the above-mentioned mutual inductance device factory man product specification.But actual conditions are, along with the instrument transformer prolongation of running time, oil level situation on the low side has appearred in the part instrument transformer, need to carry out repairing for this reason, and instrument transformer producer does not consider the problem with instrument transformer configuration repairing specific purpose tool, and this type of instrument transformer has caused certain difficulty for mutual inductor on site repairing work because the repairing hole is positioned at top; On the other hand owing to above-mentioned instrument transformer fuel filler neck and the on-the-spot employed fueling vehicle of former maintenance do not match again.Therefore, for realizing safe, reliable to the repairing of above-mentioned instrument transformer and repairing process, guarantee the safe operation of converting equipment, process the specific purpose tool that meets above two kinds of equipment repairing needs, thoroughly solve the technical barrier that the 110kV instrument transformer can not carry out repairing and be imminent.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of instrument transformer repairing instrument is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of instrument transformer repairing instrument, comprise hollow housing, described inner walls is stepped, housing is provided with vent valve and the repairing mouth with inner walls UNICOM, end at housing is provided with internal thread, switching mechanism is passed housing and is reached outside the housing, and the switching mechanism corresponding with repairing mouth and vent valve is provided with exhaust or repairing conversion mouth, and the housing other end and switching mechanism seal by sealing ring.
Above-mentioned instrument transformer repairing instrument, described switching mechanism stretch out the outer end of housing and are provided with the outer bolt cap.
Above-mentioned instrument transformer repairing instrument, the other end of described housing is provided with internal thread, and interference fit has nut in the corresponding with it switching mechanism, and nut is provided with external screw thread.
Above-mentioned instrument transformer repairing instrument is provided with three sealing rings.
Above-mentioned instrument transformer repairing instrument is provided with cone tank in the exhaust of switching mechanism or a repairing conversion mouthful side.
Adopt technique scheme, the utility model has following advantage: convenient, fast realization is to the repairing of instrument transformer, and repairing process safety, reliable is guaranteed the technical performance of insulating oil and the security of operation of equipment.The utility model solves the low maintainer of instrument transformer oil level can be expired safety at the scene, realize the technical problem that repairing maintenance and instrument transformer to equipment satisfy the safe operation needs fast, easily, for the safe operation of equipment lays the first stone.With the utility model when equipment is carried out the repairing process, the repairing operation is easy, quick, need not carry out follow-up works such as aftertreatment, reduce labour intensity, increase work efficiency, the maintainer was shortened greatly to the equipment repairing operating time, and the equipment time of putting into operation is improved, for certain contribution has been made in the raising of device security reliability service and amount of power supply.
