Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of antitheft oil-filled transformer.
Background technology
Power transformer is one of capital equipment of power plant and electric substation.The effect of transformer is many-sided, boosted voltage electric energy can not only be delivered to electricity consumption area, voltage can also be reduced to use voltage at different levels, to meet the needs of electricity consumption.In the course of work of transformer, coil can produce heat, and the heat of accumulation can damage and even burn transformer, so need installation of heat radiator, distributes the heat that coil etc. produces.
The main member of transformer is primary coil, secondary coil and iron core, the structure of such as oil-filled transformer is that the transformer core body that iron core and coil are formed is placed in device body, after the upper cover of opening device body, be easy to just iron core and coil to be put forward, this just causes some lawless persons by stealing iron core and economic interests sought by coil, have impact on the normal work of power supply-distribution system, also result in property loss.
Oil-filled transformer is exactly be immersed in inside special transformer oil by the coil of transformer and magnetic core, not only can dispel the heat but also coil and air exclusion can be made to prevent the magnetic core of the moisture in air to transformer from causing corrosion, certain arc extinguishing effect can also be played simultaneously.
Existing transformer lid is arranged on transformer shell by bolt, nut, and the radiation tooth of metal material is arranged on the outer surface of transformer shell.This way has deficiency, such as, do not possess anti-theft feature, and lawless person easily lays down bolt, nut, thus steals transformer oil, the lid in housing.And, in order to timely distribute heat, need the radiation tooth that configuration is longer, thus add the volume of transformer, install, move inconvenience; Install radiation tooth abreast at transformer shell external surface, area of dissipation is little, and radiating effect is poor.
Utility model content
The purpose of this utility model is to provide a kind of antitheft oil-filled transformer.
For reaching above-mentioned purpose, one of the present utility model embodiments provides a kind of antitheft oil-filled transformer, comprise tank body of oil tank, for the case lid of leakproof fuel cell casing and the radiator for dispelling the heat, on tank body of oil tank, edge and case lid are fixed and welded together formation hermetically-sealed construction, the winding coil being provided with iron core in tank body of oil tank and being fixed on iron core;
Guard against theft oil immersion matched transformer is equipped with vibration alarm, power-off alarm and overload alarm, and vibration alarm, power-off alarm and overload alarm are configured with the loudspeaker be arranged in tank body of oil tank.
Preferably, the short-circuit protector for the protection of circuit is configured with in tank body of oil tank.
Preferably, tank body of oil tank exterior base is provided with the bracing frame for supporting oil box body.
Preferably, the sidewall of tank body of oil tank is provided with hangers.
Preferably, tank body of oil tank is configured with the electrical connector realizing with external circuit being energized.
In sum, the utility model has the following advantages:
Tank body of oil tank and case lid are fixed and welded together by the utility model, winding coil can be allowed to be sealed in tank body of oil tank inside, guarantee when not destroying steel oil tank of transformer, case lid cannot be opened, steal winding copper material, give up the theft attempt of offender, realize the object of transformer anti-theft.
Meanwhile, the utility model have employed vibration alarm, power-off alarm and overload alarm, and vibration alarm, power-off alarm and overload alarm are configured with the loudspeaker be arranged in tank body of oil tank.Transformer body body arranges burglar alarm, enables alarm reliably realize transformer vibration alarming and power alarm.

Embodiment
The utility model provides a kind of antitheft oil-filled transformer, comprises tank body of oil tank 1, for the case lid 2 of leakproof fuel cell casing 1 and the radiator 3 for dispelling the heat.Other accessories needed for transformer can also be provided with, the equipment that the oil-filled transformers such as such as cold oil system, iron core fixation kit, iron core beam 9, folder are relevant in tank body of oil tank 1.
On tank body of oil tank 1, edge and case lid 2 are fixed and welded together formation hermetically-sealed construction, making cannot open tank body of oil tank 1 easily when not destroying transformer-cabinet, avoiding in prior art and adopting bolt to fix the defect easily opening case lid 2.The winding coil being provided with iron core 4 in tank body of oil tank 1 and being fixed on iron core 4; Both coordinate and are used for transformation.
Guard against theft oil immersion matched transformer is equipped with vibration alarm, power-off alarm and overload alarm, and vibration alarm, power-off alarm and overload alarm are configured with the loudspeaker be arranged in tank body of oil tank 1, to be sounded warning by loudspeaker.
Vibration alarm can detect the abnormal vibrations of transformer and send alarm signal.Power-off alarm can detect that transformer operation circuit voltage disappears or disconnects and send alarm signal immediately, power-off alarm can comprise power-off signal sample circuit and cut-offing alarming circuit, wherein, power-off signal sample circuit is connected to step down side two phase lines by the coil of auxiliary relay or forms between a phase line and a neutral line.Overload alarm can check whether transformer current/voltage in running transships, and sends overload-alarm when overload occurs.
In another embodiment of the present utility model, in tank body of oil tank 1, be configured with the short-circuit protector for the protection of circuit.
In another embodiment of the present utility model, tank body of oil tank 1 exterior base is provided with the bracing frame 5 for supporting oil box body 1.
In another embodiment of the present utility model, the sidewall of tank body of oil tank 1 is provided with hangers 6; Radiator is provided with vibration damping sheet 8.
In another embodiment of the present utility model, tank body of oil tank 1 is configured with the electrical connector 7 realizing with external circuit being energized; The cable of outside and inside transformer coil is convenient to connect.
