An indoor transformer fire protection system and its control method

Abstract

The invention provides an indoor transformer fire protection system and a control method thereof. The transformer includes a relay protector. The indoor transformer fire protection system includes a controller, a carbon dioxide fire extinguishing device, a temperature monitoring device and a smoke monitoring device. The carbon dioxide fire extinguishing device includes a storage device for storing The liquid carbon dioxide storage part, the injection assembly installed on the liquid storage part, and the electronically controlled switch that controls the opening and closing of the nozzle of the injection assembly. The temperature monitoring device is used to detect the temperature of the transformer, and the smoke detection device is used to monitor the indoor smoke concentration. , the controller is electrically connected with the relay protector, the temperature monitoring device and the flue gas monitoring device, and the controller is used to receive the signals sent by the relay protector, the temperature monitoring device and the flue gas monitoring device and control the electrical control according to the signals Switch on and off. The indoor transformer fire-fighting system can solve the problems of the prior art, has a simple structure and better fire-fighting 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
