Description

Waterproof alarm system for high and low voltage power equipment

technical field

The invention relates to the field of alarm devices, in particular to a waterproof alarm system for high and low voltage power equipment.

Background technique

At present, most high-voltage and low-voltage power equipment are equipped with pressure release ports or vents. If liquid substances such as water droplets fall into the pressure release ports or vents of the equipment, it is very likely to cause short-circuit explosion of the power equipment. In order to avoid the occurrence of the above situation, especially in the flood season, the operation and maintenance personnel need to frequently inspect the water leakage of the facilities above the equipment, which puts forward higher requirements for the skill level and experience of the operation and maintenance personnel. At the same time, for the investigation of leakage points, it is very difficult to conduct investigations before the rain, which leaves a relatively large safety hazard. For the single hidden leakage point that has been found, the cost of applying for a waterproof project is high and it is not easy to implement. At present, the method of covering the flood-proof film (removed after rain) is adopted. This way, the work intensity and low work efficiency of repeatedly disassembling and assembling the film are high. Covering the equipment with film will also pose a threat to the safety of personnel, equipment, and power grids.

In the specific use process, the 220V AC is rectified by the rectifier B and then sent to the measurement and control device C. The step-down board installed inside the measurement and control device C converts the above-mentioned 220V DC into 24V DC, and the above-mentioned 24V DC passes through the wire And the metal mother sheet 6 is transported to each positive electrode sheet 7, when there is a leak point in the facility (such as the roof) directly above the high and low voltage power equipment, in rainy days or other situations where the seepage liquid leaks, the seepage liquid will It drips on the electrode plastic plate 3 of the conductive device D, specifically in the V-shaped channel 31. Generally speaking, the seepage contains substances such as various inorganic salts, organic matter, silt, clay, etc., wherein Suspended and colloidal particles are mostly negatively charged, so the seepage liquid has certain conductivity. When the seepage liquid reaches a certain amount, the 24V direct current on the positive electrode sheet 7 in the seepage area will pass through the seepage liquid, the negative electrode sheet 8 adjacent to the positive electrode sheet 7, the electrode sheet wire 10, the metal The mother chip 6 and the wires are sent to the measurement and control device C, and the measurement and control device C will supply power to the sound and light alarm E, so that the sound and light alarm E operates to realize the sound and light alarm. At the same time, the measurement and control device C will also transmit the above-mentioned alarm signal to the master station system H at the dispatching end through the network switch F and the remote communication device G, so that the staff can know whether there is leakage in the equipment area at the remote end. Leaks happen. When leakage occurs, since the carrier 1b has a certain inclination angle relative to the Y-axis direction of the horizontal plane, the leakage liquid will flow down into the diversion groove 9 along the V-shaped channel 31, because the The starting end of the bottom of the diversion groove 9 is higher than the other end, that is to say the diversion groove 9 is inclined, so the seepage liquid can flow out from the right edge of the electrode plastic plate 3 smoothly, and then pass through the diversion pipe 13 discharge.

In order to improve the conductivity of the conductive device D, a sump 14 can be provided at the bottom of the V-shaped channel 31, as shown in Figure 8, a pair of positive and negative electrode sheets are inserted in each sump 14, when When there is seepage dripping, the seepage will first gather in the nearby sump 14, which improves the conductivity of the seepage in the sump 14 and ensures the positive electrode sheet 7 in the sump 14. The 24V DC power is smoothly transmitted to the measurement and control device C.

In special cases, that is, when the seepage liquid does not have conductivity or the conductivity is low, the conductive structure shown in FIG. 9 can be used to realize the conductive function, as shown in FIG. 9 . The conductive device D also includes a conductive floating body 16 made of lightweight foam material, as shown in Figure 9(b), the conductive floating body 16 is in the shape of a shuttle, that is, the middle part of the conductive floating body 16 is a cylinder shape, its two ends are cones of the same size, a copper wire 17 runs through the central axis direction of the conductive floating body 16, and the length of the copper wire 17 is greater than the length of the conductive floating body 16, in order to further improve the conductivity , at the two ends of the conductive floating body 16, that is, the cone tip of the cone is coated with a metal coating 18. In order to facilitate the fixing of the conductive floating body 16, at least one insulating wire 19 can be set, and the insulating wire 19 One end of one end is fixed on the bottom of the tank 14, and the other end is fixed on the conductive floating body 16. The length of the insulating wire 19 is required to ensure that the conductive floating body 16 can be exposed to the electrode sheet when it rises with buoyancy. Metal parts make good contact. In order to match with the conductive floating body 16, the schematic structural diagram of the electrode sheet is shown in Figure 9(a), the positive electrode sheet 7 and the negative electrode sheet 8 have the same structure, and the positive electrode sheet 7 is taken as an example for illustration here. , the positive electrode sheet 7 is scissors-shaped, that is, an inverted V-shaped hollow is set on the positive electrode sheet 7, and an electrode sheet wire 10 is provided at the end of the positive electrode sheet 7, and a group of electrode sheets are inserted into the Connected in the liquid collection tank 14, the conductive floating body 16 is arranged between the positive and negative electrode sheets, and the copper wire 17 is passed through the inverted V-shaped hollow part on the positive and negative electrode sheets, in order to ensure that there is no During leakage, the conductive floating body 16 is non-conductive, and the bottom of the positive electrode sheet 7 and the negative electrode sheet 8 in the liquid collection tank 14 is coated with an insulating coating 15. In order to prevent leakage, the conductive floating body 16 is The seepage liquid floats freely, and the size of the widest part at the bottom of the inverted V-shaped region of the electrode sheet can be limited to four times the diameter of the copper wire 17 . Figure 9(c) shows a schematic structural view of the conductive floating body 16 and the electrode sheet arranged in the liquid collection tank 14. When leakage occurs, the leakage liquid accumulates in the liquid collection tank 14, so that the conductive floating body 16 rises with the buoyancy and contacts the exposed metal part of the electrode sheet. In this way, the 24V direct current on the positive electrode sheet 7 will be transported to the Measurement and control device C.
