Fire extinguishing system for indoor transformer and control method thereof

Abstract

The invention provides a fire extinguishing system for an indoor transformer and a control method thereof. The transformer comprises a relay protection pipe. The fire extinguishing system for the indoor transformer comprises a controller, a carbon dioxide fire extinguishing device, a temperature monitoring device and a flue gas monitoring device. The carbon dioxide fire extinguishing device comprises a liquid storage part for storing liquid carbon dioxide, a spraying assembly mounted on the liquid storage part and an electric control switch for controlling a spray port of the spraying assemblyto open and close. The temperature monitoring device is used for detecting temperature of the transformer, a flue gas detection device is used for monitoring flue gas concentration indoors, and the controller is electrically connected to a relay protector, the temperature monitoring device and the flue gas monitoring device. The controller is used for receiving signals sent by the relay protector, the temperature monitoring device and the flue gas monitoring device and controlling the electric control switch to open and close according to the signals. The fire extinguishing system for the indoor transformer can solve problems in the prior art and is simple in structure and better in fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of transformer fire protection, in particular to an indoor transformer fire protection system and a control method thereof. Background technique [0002] Power safety has always been a key issue in the operation of the power grid. Therefore, power equipment will have corresponding relay protectors to protect the corresponding power equipment during operation, that is, identify power by detecting electrical or non-electrical parameters such as current and voltage of power equipment. The fault state of the equipment, and the action is to remove the faulty equipment from the grid. For example, when the transformer, which is the core equipment in the substation, fails, the relay protector will operate to trip the switches on each side (usually three sides) of the transformer to isolate the faulty transformer. [0003] With the development of the power grid and the improvement of equipment, the transformers in m...

Problems solved by technology

Once the transformer fails, it is likely to cause an electrical fire accident, which seriously threatens the safety of power supply personnel

In response to this situation, there is currently an indoor water mist fire-fighting device that starts fire extinguishing by spraying water mist from multiple angles to the transformer space configured indoors. However, this method requires the installation of large-capacity water storage tanks, water mist pumps, control The structure is relatively complicated, and the cooling, insulation, and suffocation effects of fine water mist are limited, so it cannot play a good role in fire extinguishing; moreover, general indoor water mist fire fighting devices often only pass the signal of temperature Control its action, the reliability is low, and it will also affect the fire fighting effect
