Embodiment 1

[0033] An intelligent monitoring and automatic drainage system for substation cable stratified water, such as figure 1 As shown, this embodiment includes a liquid level gauge 700, a water pump 300, a signal relay 200, an alarm device 500, a communication module 600 and a controller 400. The liquid level gauge 700 is installed in the cable layer of the substation to detect the water level in the cable layer, and the water pump 300 is installed in the cable layer, and the water pump 300 pumps the accumulated water in the cable layer to the municipal drainage facilities through the water pipe. The water pump 300 is connected to the power supply 100 through the signal relay 200, the signal relay 200, the liquid level gauge 700, the communication module 600 and the alarm The devices 500 are all connected to the controller 400 . The water accumulation in the cable layer is detected by the liquid level gauge 700, and the water accumulation data is sent to the remote end through the c...

Embodiment 2

[0041] This embodiment has carried out further modification on the basis of Embodiment 1, such as Figure 7 As shown, the water belt 311 in this embodiment also includes a water inlet head 312, the water belt 311 is a hollow cuboid, the free end of the water belt 311 is closed, and there are several gaps on both sides of the water belt 311. The water head 312; the water inlet head 312 includes a shell and a floating block 3122, the two ends of the shell are open, one end of the shell is connected to the gap, and the other end of the shell is processed with a slot 3121 along the plumb direction for clamping the floating block 3122 , the floating block 3122 is movably engaged in the slot 3121 along the vertical direction, and the floating block 3122 covers the opening area. When there is accumulated water at the water inlet head 312, the accumulated water has a buoyancy effect on the floating block 3122, thereby opening the water inlet head 312, so that the water body can enter ...

Embodiment 3

[0045] This embodiment has carried out further modification on the basis of Embodiment 1, such as Figure 8As shown, the present embodiment also includes a sludge thickness detection device including a laser transmitter 801, several laser receivers 802 and a mounting plate, the mounting plate is installed on the top of the cable layer, and several laser receivers 802 are arranged and installed on the mounting plate, The laser transmitter 801 is installed on the installation board and arranged in line with the laser receiver 802. The laser emission direction of the laser transmitter 801 has an angle with the plumb direction and is biased to the side of the laser receiver 802. The laser transmitter 801 and several laser beams The receivers 802 are all connected to the controller 400 . The control method of the sludge thickness detection device is: when the liquid level gauge 700 detects that the water level is 0, the laser transmitter 801 is periodically activated. If there is n...

Abstract

The invention relates to the technical field of substation auxiliary equipment, and particularly relates to an intelligent monitoring and automatic drainage system for the accumulated water of a cablelayer of a transformer substation. The system comprises a liquid level meter, a water pump, a signal relay, an alarm device, a communication module and a controller; the liquid level meter is installed in the cable layer of the transformer substation and detects the water level in the cable layer, and the water pump is installed in the cable layer; the water pump pumps the accumulated water in the cable layer into a municipal drainage facility through a water pipe, and the water pump is connected with a power source through the signal relay; the signal relay, the liquid level meter, the communication module and the alarm device are all connected with the controller. The system has the advantages that the accumulated water in the cable layer is detected through the liquid level meter, andthe data of accumulated water is sent to a far end through the communication module, so the timeliness and reliability of cable layer ponding monitoring are improved; the water pump base enables the water pump to break away from long-term contact with water, thereby avoiding the corrosion of water pump components, and reducing the water pump maintenance and fault probability.

Description

technical field [0001] The invention relates to the technical field of substation auxiliary equipment, in particular to an intelligent monitoring and automatic drainage system for substation cable layered water. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. Substations play the role of power hubs and dispatchers. If a substation fails, it will have a wide range of impacts and even lead to unstable operation of the power grid. Therefore, the substation needs to ensure high working reliability. In practice, the reliability of substation work is ensured through regular inspections of substation equipment. During the inspection, it was found that due to the design and engineering needs, the cable layer terrain of the general substation is about 1 meter lower than the ground level. Affected by objective reasons such as plugging mud and water seepage at the o...
