Embodiment 1

[0031] like figure 1 As shown, this embodiment provides a liquid level early warning method for preventing flooding in a power distribution room, including the following steps:

[0032] S1: The data acquisition module collects the static pressure signal detected by the liquid level sensor. Wherein, the liquid level sensor is installed outside the power distribution room and / or in a cable trench inside the power distribution room.

[0033] It should be noted that liquid level sensors can be deployed outside the power distribution room and / or in the cable trench inside the power distribution room in advance, and anti-theft and anti-sabotage measures can be taken to prevent water from flowing through the cables connected to the power distribution room. If the water level in the power distribution room enters the power distribution room through the ditch or the door of the power distribution room, it is not detected until the water level inside the power distribution room is too ...

Embodiment 2

[0056] like figure 2 As shown, this embodiment provides a liquid level early warning device for preventing water immersion in a power distribution room, including a data acquisition module 201 and a monitoring module 202, wherein:

[0057] The data acquisition module 201 is used to collect the static pressure signal detected by the liquid level sensor; convert the static pressure signal into an electrical signal; perform temperature compensation and linear correction on the electrical signal to obtain a standard electrical signal; send the standard electrical signal to Monitoring module 202; wherein, the liquid level sensor is installed outside the power distribution room and / or in the cable trench inside the power distribution room;

[0058] The monitoring module 202 is configured to convert the standard electrical signal into a water level value after receiving the standard electrical signal; when the water level value reaches the first warning threshold, control the pumpin...

Abstract

The invention discloses a liquid level early warning device and method for preventing water immersion of a power distribution room, and the method comprises the steps: collecting a static pressure signal detected by a liquid level sensor installed in a cable trench outside the power distribution room and / or inside the power distribution room through a data collection module, and converting the static pressure signal into an electric signal; performing temperature compensation and linear correction on the electric signal to obtain a standard electrical signal and sending the signal to a monitoring module, allowing the monitoring module to convert the standard electric signal into a water level value, and when the water level value reaches a first water level early-warning threshold value, allowing the monitoring module to control a water pumping system of the power distribution room to be started and send early-warning information. Therefore, the timeliness of waterproof detection of the power distribution room can be improved, and the early warning efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of power grids, and more specifically, to a liquid level early warning device and method for preventing water immersion in a power distribution room. Background technique [0002] In the power grid field, many power distribution rooms are located in low-lying places. There is a great risk of flooding in these power distribution rooms, and the distribution network equipment in the power distribution room is large and widely distributed. Once the power distribution room is flooded , There will be a risk of power outages or even electric shocks for inspectors, and there is a great potential safety hazard. Aiming at the risk of flooding in low-lying power distribution rooms, the current situation generally adopts methods such as moving the power distribution room to a higher place, manual inspection, and automatic pumping system to prevent and control, but each has certain difficulties in implementation. [000...
