Fire-proof and explosion-proof test system of extra-high voltage converter transformer and fire extinguishing method

Abstract

The invention discloses a fire-proof and explosion-proof test system for an extra-high voltage converter transformer. The fire-proof and explosion-proof test system comprises a test hall, an accidentoil drainage system, a fire extinguishing system, a smoke extinguishing chamber, a control system and a camera system; wherein the test hall comprises a test platform in the center of the hall, protection plates are arranged on four sides of the test platform, and a transformer to be tested is arranged on the platform; the accident oil drainage system comprises an oil drainage pool at the bottom of the transformer to be tested, an oil drainage pipeline below the oil drainage pool and an accident oil drainage pool; the fire extinguishing system comprises an automatic fire extinguishing device on a guardrail, a fire extinguishing device at a certain height on the wall of the hall, a water spraying system at the top of the hall and fire-fighting equipment outside the hall; the smoke extinguishing chamber is communicated with a hall and comprises a smoke exhaust fan system and a water spraying system; the control system is distributed on the outer wall of the hall; the camera system comprises a high-speed camera on a guardrail, a high-definition monitoring probe in a hall and a plurality of liquid crystal display screens in a central control room. By using the system for extinguishingfire, the fire can be effectively inhibited, and the protection level is improved.

Description

technical field [0001] The invention relates to the technical field of converter transformers, in particular to a fire-proof and explosion-proof test system and a fire-extinguishing method for an ultra-high voltage converter transformer. Background technique [0002] With the development of the national economy and the increasingly prominent problems of energy distribution and unbalanced electricity demand in our country, long-distance cross-regional power transmission and distribution from west to east has become the main strategy of my country's power system. The UHV DC transmission project has a series of advantages such as low transmission line loss, long-distance and large-capacity transmission capacity, greatly improving the utilization rate of transmission corridors, saving land resources, and strong networking capabilities, making the construction of UHV DC transmission systems a national power industry. An inevitable choice for industrial development. At present, t...
