Abstract

The invention discloses a fire unit for transformers or oil tanks comprising the control system, oil drain pipelines and nitrogen injection pipelines. The said electromagnet used for the control of the vent valve in the control system is double-action electromagnet; a mechanical interlock device is introduced in oil drain valve and nitrogen injection valve. The mechanical interlock device is a device of which the all-or-nothing piece of the oil drain valve is a cam lever, one end of even levers contacts corresponding to cam of cam levers, with the other end transmission linked with all-or-nothing piece of the nitrogen injection valve. With a pipeline leakage collection plate on oil drain pipeline of micro-leakage windows and a dropper on the leakage collection plate corresponding to the window glass. The invention is a fire unit used in transformers and oil tanks, overcomes the deficiencies of oil-drained nitrogen injected fire unit on current markets, more reliable, simple in structure and convenient to produce.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a fire extinguishing device for an oil-immersed transformer and an oil tank. Background technique [0002] The oil discharge and nitrogen injection fire extinguishing system for transformers and oil tanks is composed of control system, fire cabinet, shut-off valve, oil discharge pipeline, nitrogen injection pipeline, etc. It is used for oil-immersed transformers and oil tanks with explosion-proof and fireproof and fire extinguishing device. The oil discharge pipeline is connected to the upper part of the transformer, and the oil discharge valve controls the oil discharge and pressure relief of the system, mainly including the oil discharge pipeline, oil discharge valve, maintenance valve, expansion joint, etc. Iron control, the electromagnet is controlled by the control system to turn on. The nitrogen injection pipeline is connected to the high-pressure nitrogen cylinder and the t...
