Problems solved by technology

[0002] After a fire broke out in the transformer, the main body could not be approached because of the fire, so it was impossible to artificially activate the oil discharge valve to drain the oil from the transformer
Moreover, the oil discharge valve is extremely prone to failure at high temperature, which makes it impossible to open the oil discharge valve to discharge oil from the transformer

Abstract

The invention discloses an oil draining valve of a transformer, and the transformer. The oil draining valve of the transformer comprises a fireproof cabinet body, an electric oil draining valve, a fireproof wire and a controller, wherein the controller is used for controlling the opening or closing of the electric oil draining valve; the front end and the rear end of the fireproof cabinet body arecorrespondingly provided with a first opening and a second opening; the electric oil draining valve is arranged inside a chamber of the fireproof cabinet body; an oil inlet and an oil outlet of the electric oil draining valve correspondingly penetrate through the first opening and the second opening and are fixed to the first opening and the second opening; the side surface of the fireproof cabinet body is provided with a third opening; one end of the fireproof wire is electrically connected with a signal input end of the electric oil draining valve after penetrating through the third opening; and the other end of the fireproof wire is electrically connected with a signal output end of the controller. The oil draining valve disclosed by the invention can realize remote control on openingand closing of the electric oil draining valve so as to realize remote oil drainage; and the electric oil draining valve can be prevented from being damaged due to high temperature by virtue of the fireproof cabinet body.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a transformer oil discharge valve and a transformer. Background technique [0002] After a fire broke out in the transformer, the main body could not be approached because of the fire, which made it impossible to artificially activate the oil discharge valve to discharge oil from the transformer. Moreover, the oil discharge valve is extremely prone to failure at high temperatures, resulting in the inability to open the oil discharge valve to discharge oil from the transformer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transformer oil discharge valve and a transformer to realize the effect of remotely opening the oil discharge valve in view of the deficiencies in the prior art. [0004] In order to solve the above technical problems, the present invention provides a transformer oil discharge valve, including ...
