Abstract

The invention discloses a pressure-relief anti-oil-leakage protective capacitive voltage transformer device which comprises: an oil tank composite body, a lower capacitive voltage divider, a terminalboard, a support main pole, an upper capacitive voltage divider, an electromagnetic unit, and an output wiring slot. The oil tank composite body is installed under the electromagnetic unit and is fastened to the electromagnetic unit. The output wiring slot is disposed under the electromagnetic unit and is electrically connected with the electromagnetic unit. When the device is used, by means of the oil tank composite body, the problems can be avoided that when the magnetic flux on the transformer is not uniform, the high temperature causes a sealing ring in the oil tank to gradually age and thus causes an oil tank casing to expand and leak oil so as to affect the normal operation of the transformer, and that when the large current flows through the electromagnetic sleeve, the transformer is likely to generate heat and causes a great voltage drop so as to damage to components. Thus, the device can prevent the oil leakage and the structural safety of the transformer.

Description

technical field [0001] The invention relates to a capacitive voltage transformer device for pressure relief and anti-oil leakage protection, which belongs to the field of voltage transformer equipment. Background technique [0002] With the rapid development of high-voltage transmission technology, in order to provide reactive power compensation, enhance system stability and improve voltage quality, capacitive voltage transformers are often used. Capacitive voltage transformers are divided by series capacitors and then electromagnetically A type of voltage transformer for step-down and isolation, relay protection, etc. [0003] The existing technology has the following disadvantages: when the magnetic flow on the transformer is not uniform, the excessive magnetic flow will lead to high temperature, and the high temperature will gradually age the sealing ring in the fuel tank, resulting in the expansion of the fuel tank shell and oil leakage, which will affect the transformer...
