    Abstract: In order to get over the problem of insufficient monitoring accuracy and poor timeliness of the fire protection monitoring system of the converter valve hall, a fire protection monitoring device suitable for the valve tower was developed, which can monitor the state of the internal components of the valve towers in real time and detect fires in time. In order to evaluate the electromagnetic shielding characteristics of the valve tower fire monitoring device in a complex electromagnetic environment, the equivalent transmission method is used to calculate the electromagnetic shielding effectiveness of the device, and the shielding effectiveness value is obtained to meet the requirements of use. The prototype of the fire protection monitoring device was trial-produced, and the key imaging technology of the fire protection monitoring device was tested and verified. The results showed that the device fully meets the requirements of engineering use and can greatly improve the accuracy of fire monitoring.
    Key words: valve tower; fire monitoring device; equivalent transmission method; effectiveness of electromagnetic shielding
