Problems solved by technology

This manual start-stop mode has the following disadvantages: (1) Increases the labor intensity of operators
(2) When the temperature of the main transformer rises due to the increase of the load or the change of the ambient temperature, the air cooling system cannot be started in time for cooling, so that the temperature rise of the main transformer is too high and the service life of the main transformer is reduced. In severe cases, the main transformer may be burned. major accident
On the other hand, when the main temperature drops, the air-cooling system cannot be shut down in time, resulting in a large waste of electric energy.

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] The invention discloses an air-cooling device for a transformer, which is used for cooling a transformer in a substation. The following are specific embodiments:

[0016] An air-cooling device for a transformer in the present invention includes a cooling fan driven by a motor and an automatic control system for controlling the motor. The air-cooling device uses a cooling fan to air-cool the transformer, which can ensure safety and is easy to control.

[0017] The automatic control system in the present invention includes a temperature sensor Z for measuring the temperature of the transformer, a single-chip microcomputer U1 connected to the temperature sensor Z, and a solid-state relay R whose triggering state is controlled by the single-chip microcomputer U1. The temperature sensor Z is set on the outer casing of the transformer to measu...

Abstract

The invention discloses an air cooling device of a transformer, belonging to the technical field of transformer cooling equipment. Includes a cooling fan driven by a motor and an automatic control system for controlling the motor; The automatic control system comprises a temperature sensor Z for measuring the temperature of the transformer, a single-chip microcomputer U1 connected with the temperature sensor Z and a solid-state relay R for controlling the triggering state by the single-chip microcomputer U1. The automatic control system comprises a temperature sensor Z for measuring the temperature of the transformer, a single-chip microcomputer U1 connected with the temperature sensor Z and a solid-state relay R. The motor is connected to a three-phase power supply through a solid state relay R. A solid state relay is used to control the on-off between the cooling fan and the three-phase power supply, and the SCM and temperature sensor are used to control the triggering state of the solid state relay, The setting improves the measurement accuracy of the temperature of the transformer and can adjust the cooling fan according to the real-time temperature of the transformer, which can not only ensure the cooling effect of the transformer but also prevent the waste of energy and the reduction of the life of the cooling fan caused by the fact that the cooling fan is always in a start-up state.

Description

technical field [0001] The invention relates to an air cooling device for a transformer, belonging to the technical field of transformer cooling equipment. Background technique [0002] At present, in order to reduce the operating temperature of the main transformer in the substation, a forced air cooling system is usually installed for the main transformer. The operation of the air-cooling system adopts the manual start-stop mode. This manual start-stop mode has the following disadvantages: (1) It increases the labor intensity of the operators. (2) When the temperature of the main transformer rises due to the increase of the load or the change of the ambient temperature, the air cooling system cannot be started in time for cooling, so that the temperature rise of the main transformer is too high and the service life of the main transformer is reduced. In severe cases, the main transformer may be burned. turned into a major accident. On the other hand, when the main tempe...
