Embodiment Construction

[0037] see figure 1 -7, those skilled in the art should understand that in the disclosure of the present invention, the orientations or positional relationships indicated by the terms "upper", "lower", "one end", "another end" etc. are based on the drawings The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, so the above terms should not be interpreted as Limitations on the Invention.

[0038] It should be noted that if a fire occurs in a low-oil equipment, the existing fire extinguishing method is to move the fire extinguishing device to the vicinity of the fire equipment, isolate and protect the fire equipment, reduce the impact of environmental wind, accurately locate the fire source and spray the fire extinguishing agent, w...

Abstract

The invention discloses a dry powder supply device for a fire extinguishing device of a transformer substation. The dry powder supply device comprises a first mixing device, a first supercharging device and dry powder extinguishers, wherein the first mixing device is provided with a mixing cavity and an outlet and is used for being connected with a target fire extinguishing nozzle; one end of thefirst supercharging device is connected with the first mixing device, and the first supercharging device is used for supercharging the first mixing device; and the multiple dry powder extinguishers are connected with the first mixing device, and dry powder of the dry powder extinguishers can be mixed through the mixing cavity of the first mixing device. When the dry powder supply device is used, the dry powder of the dry powder extinguishers is sprayed out and enters the mixing cavity of the first mixing device, the dry powder is pressurized through the first pressurizing device and supplied to the target fire extinguishing nozzle through the outlet to achieve fire extinguishing, and the multiple dry powder extinguishers are arranged to continuously supply the dry powder to the fire extinguishing nozzle; and during fire extinguishing, only the used dry powder extinguisher needs to be replaced, and when the used dry powder extinguisher is replaced, the other dry powder extinguishers canstill extinguish fire, so that continuous fire extinguishing is realized.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a dry powder supply device for a substation fire extinguishing device. Background technique [0002] In order to facilitate metering, measurement and protection of electrical equipment, some oil-less equipment will be installed in the substation, such as oil-immersed voltage and current transformers, etc., which contain a certain amount of insulating oil. For example, the single-phase oil weight of a 110kV current transformer is about 100kg , 220kV current transformer single-phase oil weighs about 200kg, 500kV current transformer single-phase oil weighs about 700kg, the flash point of insulating oil is 135-150°C, the ignition point is 165-195°C, and the spontaneous ignition point is about 332°C. high. If a fault occurs inside the equipment, the insulating oil will decompose into flammable gases such as methane, ethane, hydrogen, etc., and the body of the device will burst after the...
