Abstract

The utility model discloses a sealing device for a secondary terminal of a voltage transformer. According to the key points, the sealing device comprises a sealing sleeve, wherein the top end of the sealing sleeve is tapered, and the tapered top part is provided with a mounting hole. The sealing sleeve is matched with the secondary terminal of the voltage transformer in size. The sealing device further comprises a sealing rubber ring, a flat cushion and nuts. The sealing device is simple in structure. The secondary terminal of the voltage transformer is provided with the sealing device to seal the secondary terminal in the sealing device, so that the dampness and the oil leakage can be prevented, the service life of the sealing device is greatly prolonged, and the maintenance cost is reduced.

Description

A kind of Secondary Connections of PTs end sealing device
Technical field
The utility model relates to a kind of Secondary Connections of PTs end sealing device.
Background technology
Existing Secondary Connections of PTs end be generally directly exposed outside, service life of a specified duration after, in case the problems such as material aging or leakage of oil occur occurring because making moist, just need to change the secondary connection end, the method for generally taking is that whole instrument transformer is hung oneself, drained the oil, suspended core, then changes secondary wiring terminals from electrical network.These work meetings produce a large amount of maintenance costs, and complicated operation.
The utility model content
The purpose of this utility model is to provide a kind of Secondary Connections of PTs end sealing device.
To achieve these goals, by the following technical solutions, a kind of Secondary Connections of PTs end sealing device is characterized in that: described sealing device comprises sealing shroud, and sealing cover top is tapered, and conical top has an installing hole.
Described sealing shroud size adapts with the secondary connection end of voltage transformer.
Described sealing device also comprises O-ring seal, plain cushion and nut.
The utility model is simple in structure, for the secondary connection end of voltage transformer arranges a sealing device, makes the secondary connection end can be sealed in wherein, can prevent from making moist and leakage of oil, has improved greatly its useful life, reduces maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the assembly structure figure of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As depicted in figs. 1 and 2, a kind of Secondary Connections of PTs end sealing device comprises sealing shroud 1, and sealing cover 1 top is tapered, and conical top has an installing hole.Described sealing shroud 1 size adapts with the secondary connection end 6 of voltage transformer 2.Described sealing device also comprises O-ring seal 2, O-ring seal 3, plain cushion 4 and nut 5.
During use, at first O-ring seal 2 of cover on secondary connection end 6, be placed on the facial planes of secondary connection bottom it.Then O-ring seal 3 is positioned in the conical top of sealing shroud 1, and sealing shroud 1 is enclosed within on secondary connection end 6, make the secondary connection end be housed in sealing shroud.At last, tighten up with plain cushion 4 and nut 5 on sealing shroud 1 top, make the plane of whole sealing shroud and secondary connection bottom section tightly seal by O-ring seal 2, tightly seal and pass through O-ring seal 3 between secondary connection end top and sealing shroud.
The utility model is simple in structure, for the secondary connection end of voltage transformer arranges a sealing device, makes the secondary connection end can be sealed in wherein, can prevent from making moist and leakage of oil, has improved greatly its useful life, reduces maintenance cost.
