Embodiment approach

[0026] The closed lightning temperature of the transformer oil tank is 135 ℃ ~ 140 ℃. The fire extinguishing device is equipped with a temperature-sensitive fusible alloy to control the starter of the temperature-sensitive magnetic generator. The action temperature of the fire extinguishing device is set to 145 ℃. A gas fire extinguishing control panel is set up on site, and a fire extinguishing control panel is set up in the main control room.

[0027] First calculate the net space required for transformer fire extinguishing, calculate the amount of fire extinguishing agent according to the fire extinguishing design concentration of relevant national standards, and calculate how many dry powder fire extinguishing devices are needed in total. Then, according to the two sides of the long side of the transformer, both sides of the short side, and the three positions of high, middle and low, fire extinguishing devices are allocated according to twelve positions, and finally the fi...

Abstract

The invention relates to a transformer superfine dry powder extinguishing method and device. The technical scheme is as follows: a plurality of extinguishing devices are mounted on a transformer outer side (9); each extinguishing device consists of an extinguishing device body (1), a blasting membrane (2), superfine dry powder (3), a temperature sensing magnetic generator (4), a cable (5), an ignition controller (6) and a fixing gold tool (7); extinguishing agent is the superfine dry powder; when the periphery of the transformer reaches the predetermined fire temperature, the extinguishing devices are sprayed to the whole body of the transformer (8); the superfine dry powder is sprayed in different positions of the transformer to implement the total-flooding extinguishment. The transformer superfine dry powder extinguishing method and device have the advantages of low cost, quick speed, no recrudescence and environmental protection; the extinguishing devices are close to protected objects to quickly extinguish the fire in the bud, so that the loss caused by the fire is effectively reduced, and the production is conveniently recovered. Field staff cannot be hurt during releasing; the transformer superfine dry powder extinguishing method and device are most suitable for unmanned duty stations or key protection departments.

Description

technical field [0001] The patent of the invention relates to a transformer superfine dry powder fire extinguishing method and device, belonging to the technical field of transformer fire protection. Background technique [0002] At present, my country's transformers above 220KV are equipped with oil discharge nitrogen injection type transformer fire extinguishing device or foam spray fire extinguishing device according to the requirements, and above 500KV are equipped with foam spray fire extinguishing device or oil discharge nitrogen injection type transformer fire extinguishing device, and 110KV is installed with oil discharge injection type. The nitrogen-type transformer fire extinguishing device has a local standard (issued by Hunan Provincial Bureau of Technical Supervision), and 110KV and above transformers have realized alarm and fire extinguishing. However, the foam spray fire extinguishing device has the problem of long pipelines, large firefighting room and other l...
