Substation water level detection device

Abstract

The invention discloses a substation water level detection device, and relates to the field of alarm devices. The device is characterized in that a transformer is arranged on a pit, and a detection device for detecting the water level of a substation is arranged on one side of the transformer, and the device is characterized in that the detection device comprises a detection assembly, a power source and a pressure assembly, the detection assembly comprises a fixing frame arranged on the side wall. the fixing frame is provided with a semi-threaded shaft, a sleeve is hung on the semi-threaded shaft, a nylon rope is arranged in the sleeve and penetrates through the sleeve, one end of the nylon rope is connected with a warning water absorption block and a failure water absorption block, the other end of the nylon rope penetrates through the sleeve and is fixedly connected with a fixing ring arranged on the side wall, and the height of the fixing ring is the same as that of the warning water absorption block. One end of the sleeve is connected with the control device in an abutting way, and the control device is triggered to control an alarm device and a driage device to work through the lever principle. The device has the technical effects that the reliability of the detection element is high, the interference capability is high, the detection element is not affected by the voltageof a transformer substation and corroded by accumulated water, the detection element is not prone to damage, and information transmission is accurate.

Description

technical field [0001] The invention relates to the field of application alarm devices, in particular to a substation water level detection device. Background technique [0002] The further acceleration of the urbanization process has led to an increase in the density of urban buildings, a sharp increase in hardened road surfaces, a weakening of the ground's infiltration function, and the continuous rise of urban building foundations, resulting in no obvious height difference between the ground floor of the equipment area of ​​some old substations in operation and the surrounding terrain , even lower than the surrounding site, and reduced to a low-lying area, the substation is prone to water infiltration due to heavy rain. The bottom of the substation is designed as a slope to guide water to one place for easy drainage. [0003] With the reform and development of power grid technology, many substations are unattended. When there is heavy rain, water will accumulate in the lo...

AI Technical Summary

Problems solved by technology

[0003] With the reform and development of power grid technology, many substations are unattended. When there is heavy rain, water will accumulate in the lower part of the slope pit in the substation. The main station staff cannot grasp the water level of the substation in time and need to be manually opened one by one. For power stations, investigations are labor-intensive and cannot be conducted in a timely manner, thus missing the opportunity to take relevant measures and causing greater losses. It is necessary to design a water level detection device in the slope pit

[0004] Existing water level detection devices using metal electrodes are widely used for detection. By applying a voltage between two metal electrodes, the presence or absence of water level is determined according to the voltage between the two electrodes. However, the substation itself has a huge voltage, and the detection device will be affected. Interference, resulting in inaccurate detection results, causing huge losses and when there is water accumulation, it takes a long time for the staff to rush to the substation to drain the water, and the metal electrodes are placed in the water for a long time, which is easy to corrode and electrolyze, which affects the detection accuracy
