Abstract

The utility provides a substation deicer which uses heated air for deicing and consists of movable equipment, a blower, a heater and a hot air output pipe; the movable equipment is capable of freely moving near to poles and towers, conducting wires and insulators which are covered with ice in a substation; the blower is capable of speeding up air flow, thus forming cold air; the heater is capable of heating the cold air into hot air; the hot air output pipe is capable of blowing the hot air to different positions of the ice-covered poles and towers, conducting wires and insulators in different directions. The substation deicer eliminates the threat of pole and tower collapse accidents to worker life safety when manual deicing, greatly improves deicing efficiency, is simple and convenient to operate and is capable of deicing with electricity without power cut in the substation.

Description

A kind of transformer station deicer

Technical field

The utility model relates to a kind of transformer station deicer.

Background technology

When meeting with long-term frosty weather, the shaft tower in the transformer station, lead and insulator surface have icing and occur.The insulator surface icing causes the insulator edge flashing easily, causes that the short trouble of electric power system takes place.Shaft tower and wire icing can increase the stressed load of shaft tower, can cause the generation of shaft tower collapse accident when serious, cause transformer station to stop transport.At present transformer station mainly adopts the method for artificial deicing, utilizes manpower that shaft tower, lead and the insulator of icing carried out machinery and beats and icing is come off.When top, lead and suspension insulator to shaft tower carry out deicing, also need operating personnel's work high above the ground.Therefore not only efficient is low for this de-icing method, and causes the damage of circuit and insulator easily, the more important thing is, if the shaft tower collapse accident takes place when operation, and life security that will the serious threat operating personnel.

Summary of the invention

The purpose of this utility model is to provide a kind of transformer station deicer, and is simple, convenient, deicing efficiency is high, and the shaft tower collapse accident is to the threat of operating personnel's life security when having eliminated artificial deicing.

The technical solution of the utility model is: a kind of transformer station deicer is characterized in that: comprise movable equipment, air blast, heater and hot blast efferent duct; Air blast is connected with heater, and all is installed on the movable equipment, and the hot blast efferent duct is connected above the heater.

Aforesaid transformer station deicer is characterized in that: hot blast efferent duct bottom is equipped with and turns to and telescoping mechanism.

Aforesaid transformer station deicer is characterized in that: the hot blast efferent duct adopts the insulation and thermal insulation material.

The beneficial effects of the utility model are: the shaft tower collapse accident was to the threat of operating personnel's life security when (1) had eliminated artificial deicing, (2) improved the efficient of deicing greatly, (3) simple, convenient, (4) can charged deicing under the situation that transformer station does not have a power failure.

Description of drawings

Fig. 1 is the fundamental diagram of the utility model embodiment.

Embodiment

Below in conjunction with drawings and Examples the utility model transformer station deicer is described further.

Mark among Fig. 1: 1-movable equipment, 2-air blast, 3-heater, 4-hot blast efferent duct.

The utility model embodiment transformer station deicer comprises movable equipment 1, air blast 2, heater 3 and hot blast efferent duct 4; Air blast 2 is connected with heater 3, and all is installed on the movable equipment 1, and hot blast efferent duct 4 is connected above the heater 3.

Movable equipment 1 wherein is the loading appliance of deicer, can be free to travel to shaft tower, lead and the insulator of icing in the transformer station along the line walking circuit near; Air blast 2 is air force parts of deicer, and effect is to quicken flowing of air, and air blast can also be by regulating the size of rotating speed of motor control speed air flow; Heater 3 is thermals source of deicer, both can burning coal, oil, natural gas produce heat, also can produce heat by consumed power, according to the measurement feedback information of built-in temperature sensor, heater 3 can be by regulating the height of how much controlling the heated air temperature that produces heat; Hot blast efferent duct 4 adopts the insulation and thermal insulation material, thermal insulation can improve energy utilization rate, insulation then helps carrying out deicing under the situation that transformer station does not have a power failure, hot blast efferent duct 4 bottoms are equipped with steering mechanism, hot blast efferent duct 4 is freely turned to, hot blast efferent duct 4 can also freely stretch, and makes that like this diverse location on icing shaft tower, lead and the insulator of different azimuth all can be blown to by hot blast.

During concrete enforcement, movable equipment 1 moves along the line walking route in the transformer station, and when near the shaft tower, lead or the insulator that arrive icing, movable equipment 1 stops to move; Air blast 2 is regulated rotating speed of motor according to control signal, makes air flows accelerate to certain speed, forms cold wind; The cold wind that heater 3 is brought air blast 2 is heated to certain temperature becomes hot blast; Hot blast efferent duct 4 is flexible to required length, and by steering mechanism regulate the hot blast output mouth of pipe right direction, the hot blast of heater 3 heating is blown on the diverse location of icing shaft tower, lead and insulator.

Claims
