Isolation transformer based on power network security system

Abstract

The invention discloses an isolation transformer based on a power network safety system, and the isolation transformer comprises an oil tank, an isolation plate and an oil conservator; a movable cavity is formed in the isolation plate, a heat conduction piece is fixedly connected to the lower portion of the movable cavity, and a piston block is movably connected to the interior of the movable cavity; and a mercury layer is arranged on the lower side of the piston block in the movable cavity. By designing the movable cavity, the piston block, the mercury layer, the large air bag, the heat conducting piece, the air outlet groove and the air outlet pipe, heat generated in the oil tank is transmitted to the mercury layer in the movable cavity through the heat conducting piece, so that the mercury layer is heated to rise to drive the piston block to move upwards and extrude the large air bag; the large air bag releases air in the large air bag through the air outlet groove and the air outlet pipe to take away heat on the heat-conducting fins, and heat dissipation of the heat-conducting fins is accelerated; meanwhile, the flowing of air flow in the air outlet pipe can take away heat of cooling oil outside the air outlet pipe, and heat dissipation of the cooling oil in the oil tank is further accelerated.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to an isolation transformer based on a power network security system. Background technique [0002] The isolation transformer is a transformer with electrical isolation between the input winding and the output winding. It is mainly used to avoid accidental contact with the charged body at the same time. The isolation transformer is a safe power supply. The main purpose is to prevent interference. It is widely used in subways, high-rise buildings, Power transmission and distribution of airports, stations, docks, industrial and mining enterprises, and tunnels. [0003] Since the loss in the winding and iron core of the transformer is released in the form of heat during the operation of the transformer, this heat must be dissipated in time to prevent the internal overheating of the transformer from aging and damage the insulation layer inside the transformer. At present, the heat ...
