Description
Technical field
The utility model is related to a kind of transforming plant main transformer temperature controller thermometer bulb pedestal water-inlet-proof structures, and it is anti-to belong to transformer
Protect technical field.
Background technology
Main transformer temperature controller thermometer bulb need to be inserted into thermometer bulb pedestal in substation, and pedestal is previously implanted into some transformers oil,
After being inserted into thermometer bulb, oil is made to be full of.But the sealing between the helix tube of the extracapillary of temperature controller and thermometer bulb screw socket is not
It is very tight, sleet season is arrived, sleet water can flow into thermometer bulb pedestal along the gap between helix tube and thermometer bulb pedestal screw socket, due to water
Density is more than the density of oil, oily " crowded " can be gone out pedestal and form oil water mixture, improve freezing point, or even the freezing point close to water.It arrives
Winter, rural area load are generally reduced, and some main transformers are out of service, at ambient temperature, the oil water mixture in thermometer bulb pedestal
Will freezing and expansion, spalling thermometer bulb pedestal make transformer-cabinet interior insulation oil from thermometer bulb overflow, cause a large amount of oil leaks, and thermometer bulb
The dielectric strength that insulating oil is reduced in interior oil water mixture meeting inflow transformer, causes equipment safety hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of transforming plant main transformer temperature controller thermometer bulb pedestal water-inlet-proof structure, prevents
Thermometer bulb pedestal and spiral water inlet tube, ensure the operational safety of equipment, reduce the frequent maintenance of equipment, solve background technology and exist
The above problem.
The technical solution of the utility model is：
A kind of transforming plant main transformer temperature controller thermometer bulb pedestal water-inlet-proof structure, including capillary, helix tube, thermometer bulb, temperature
Packet pedestal, insulating tape, fixed screw, heat-shrink tube and transformer, the thermometer bulb pedestal are arranged in transformer top, thermometer bulb pedestal
Interior to be equipped with internal thread, thermometer bulb lower part is equipped with external screw thread, and thermometer bulb is connected with thermometer bulb whorl of base, and is fastened by fixed screw；
The upper end of thermometer bulb is connected with capillary, and extracapillary is arranged with helix tube；Insulating tape wind respectively setting helix tube with
The junction of the junction and thermometer bulb pedestal and thermometer bulb lower part of thermometer bulb upper end；Heat-shrink tube is wrapped in helix tube, thermometer bulb, thermometer bulb pedestal
With insulating tape outside.
The length of the heat-shrink tube is 50cm.
Thermometer bulb is taken out, thermometer bulb pedestal, injection transformer oil are cleared up；It is appropriate that thermometer bulb and helix tube are inserted in about 50cm long
The heat-shrink tube of bore；Thermometer bulb is inserted into thermometer bulb pedestal, so that transformer oil is full of or is slightly overflowed, tightens fixed screw by thermometer bulb
It is fixed；It draws back heat-shrink tube and is allowed to one end and entangle thermometer bulb pedestal, the other end is more than the peak of helix tube；Heat is heated with electric heat gun
The draw, which is allowed to shrink, wraps helix tube and thermometer bulb pedestal.
The good effect of the utility model：Going deep into for sleet water is effectively prevented, reduces the generation of accident, improves
The safety of equipment operation, reduces plant maintenance workload.
