Device for compensating pressure of transformer cooling oil liquid on basis of effect

Abstract

The invention discloses a device for compensating pressure of transformer cooling oil liquid on the basis of effect. The device comprises a capsule-shaped body, an overlapped plate (1) and a guiderail (5), wherein the capsule-shaped body is filled with transformer cooling oil liquid and the volume of the capsule-shaped body can be changed; the overlapped plate (1) is arranged on the capsule-shaped body and is used for supporting the capsule-shaped body and driving the capsule-shaped body to move; and the guiderail (5) is connected with the overlapped plate (1). The overlapped plate (1) drives the capsule-shaped body to move along the guiderail (5), so that oil liquid in a cooler of a transformer is compensated and the condition of only using an oil conservator body prevented; therefore the performance requirements for the compensation and cooling of the transformer cooling oil liquid are satisfied.

Description

1. Technical field [0001] The invention relates to a compensating device, in particular to a compensating device based on the pressure of the cooling oil of a transformer. 2. Background technology [0002] Transformer is an important pivotal equipment in the power system. The oil conservator is an important protective device for oil-immersed transformers. It is a compensation container necessary to meet the volume change of insulating oil due to temperature changes, that is, thermal expansion and contraction. For 35KV The above oil-immersed transformers require the oil conservator to be fully sealed, that is, the insulating oil is isolated from the atmosphere to prevent the water and oxygen in the air from dampening and aging the insulating oil, which affects the insulation performance; when the oil-immersed transformer is running, the internal winding, iron core and other parts produce loss. The loss is converted into heat and transferred to the oil tank wall through the h...

Problems solved by technology

The temperature rise directly affects the life of the winding insulation material, so the temperature rise must be controlled within a certain range, and it is also necessary to use a radiator for heat dissipation. Therefore, the compensation device based on the heat dissipation oil pressure of the transformer is an important transformer. In the existing compensating device based on the heat dissipation oil pressure of the transformer, the transformer needs two devices, the oil conservator and the disc, to realize the volume compensation and heat dissipation function of the transformer insulating oil, and there are inaccurate oil level indication and If the heat dissipation effect is not good, there is no device that can not only compensate the oil volume of the transformer but also play a role in heat dissipation, thereby simplifying the heat dissipation device of the transformer
