Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power stations, and in particular to a power consumption monitoring system for an energy storage power station. Background Art

[0002] With the rapid development and popularization of renewable energy, energy storage power stations, as an important energy conversion and storage equipment, are gradually becoming an indispensable part of the power system. Energy storage power stations have many advantages such as being able to store energy, adjust grid loads, and improve grid stability.

[0003] However, the current power consumption monitoring of energy storage power stations has always been a difficult point. On the one hand, traditional power consumption monitoring systems often cannot accurately monitor the real-time power consumption of energy storage power stations, resulting in energy waste and low efficiency. On the other hand, due to the frequent charging and discharging process in the actual operation of energy storage power stations, the collection and analysis of power consumption data also have certain difficulties and uncertainties. The energy meter is a common device in the power consumption monitoring system and is widely used in the power consumption monitoring system. Due to the need for monitoring accuracy, each electrical equipment usually needs to be monitored separately using at least one energy meter, and the number of electrical equipment in energy storage power stations is large, so the installation of energy meters is a very huge workload.

[0041] The electric energy meter 2 of the present invention adopts a plug-in structure to be arranged in the electric energy meter box 1, which can simplify the wiring process and bring convenience to the later operation and maintenance. At the same time, a protection structure and an arc extinguishing structure are provided, which can automatically extinguish the arc when the electric energy meter 2 is disconnected, thereby improving safety.

When rising, the connection pole 8 of the electric energy meter 2 is separated from the connection slot 7, and it is in a disconnected state. When the electric energy meter 2 moves down, the connection pole 8 at its bottom is inserted into the connection slot 7 and connected to the cable in the wire trough 5, so that the electric energy meter 2 is connected to the electrical equipment of the energy storage power station, and the power consumption can be monitored.

[0045] When the electric energy meter 2 needs to be inspected, the electric energy meter 2 is directly lifted up, and the end 11 thereon can be inserted into the card frame 10. The card pin 12 is connected to the card frame 10, so that the electric energy meter 2 can be fixed in a high position to facilitate its inspection and repair. If disassembly is required, the electric energy meter 2 is removed as a whole along with the guide rail 3 and the fixing frame 9.

[0046] A limiting groove 14 is provided in the lifting seat 4, and the top end of the rack 13 is slidably connected in the limiting groove 14, and the rack 13 is connected to a first spring 15, and the top end of the rack 13 is connected to a push head 16, and a rolling member 17 is provided on the push head 16. A baffle 18 is provided in the meter box 1, and when the rolling member 17 moves onto the baffle 18, the rack 13 moves in the limiting groove 14.

[0047] When the electric energy meter 2 moves up and down, the lifting seat 4 thereon moves accordingly. The rack 13 on the lifting seat 4 can be used as a driving structure to open the protective cover 21 in the electric meter box 1. Before opening the protective cover 21, the grid 26 in the protective cover 21 is first dispersed. This dispersion process is performed when the electric energy meter 2 is disconnected, which can effectively improve the arc extinguishing effect.

[0048] A guide seat 25 is provided on the top of the protective cover 21, and a grid sheet 26 is connected to the guide seat 25, and pins 27 are provided at intervals on the grid sheet 26. A traction block 28 is slidably installed on the side wall of the protective cover 21, and a push plate 29 is fixedly connected to the traction block 28, and a cone head 30 is provided on the push plate 29, and the cone head 30 is set in the gap of the grid sheet 26. A second spring 31 is fixedly connected to the traction block 28, and a reel 32 is rotatably installed on the assembly seat 19, and a lower gear 33 and a traction rope 34 are fixedly connected to the reel 32, and the traction rope 34 is fixedly connected to the traction block 28.

[0049] The grid 26 is elastically mounted through the guide seat 25 and can move. When the lifting seat 4 drives the rack 13 to move upward, the rack 13 initially engages with the lower gear 33, which can drive the lower gear 33 and the reel 32 to rotate. The reel 32 winds the traction rope 34 thereon, thereby pulling the traction block 28. The push plate 29 on the traction block 28 moves, pushing the cone head 30 into the gap of the grid 26, so that the grid 26 is actively dispersed, and the arc is extinguished more effectively when an arc occurs.

The rack 13 is pushed by the blocking bar 18 and meshes with the driving gear 24.

[0051] After the energy meter 2 completes the disconnection and arc extinguishing work, the energy meter 2 will continue to move upward. At this time, the rack 13 is disengaged from the lower gear 33, and the rolling element 17 moves to the baffle 18, thereby overcoming the elastic force of the first spring 15 to push the rack 13, so that the rack 13 moves to a state of meshing with the driving gear 24. The driving gear 24 drives the switching gear 22 to rotate in the opposite direction, thereby rotating the protective cover 21 open through the switching shaft 20, so that the power connection structure is exposed, which is convenient for maintenance and management.

[0052] When the present invention is in use: first, when the electric energy meter 2 needs to be repaired, the electric energy meter 2 is directly lifted up, and the end 11 thereon can be inserted into the card frame 10, and the card pin 12 is connected to the card frame 10, so that the electric energy meter 2 can be fixed at a high position, which is convenient for its inspection and repair. If disassembly is required, the electric energy meter 2 is removed as a whole along with the guide rail 3 and the fixing frame 9. When the electric energy meter 2 moves up and down, the lifting seat 4 thereon moves accordingly, and the rack 13 on the lifting seat 4 can be used as a driving structure to open the protective cover 21 in the electric meter box 1, and before opening the protective cover 21, the grid 26 in the protective cover 21 is first dispersed. This dispersion process is performed when the electric energy meter 2 is disconnected, which can effectively improve the arc extinguishing effect. The grid 26 is elastically installed through the guide seat 25, and it can move. When the lifting seat 4 drives the rack 13 to move up, the rack 13 opens The spool 32 is meshed with the lower gear 33, which can drive the lower gear 33 and the reel 32 to rotate. The reel 32 winds the traction rope 34 thereon, and then pulls the traction block 28. The push plate 29 on the traction block 28 moves, and the cone head 30 is pushed into the gap of the grid 26, so that the grid 26 is actively dispersed, and the arc is extinguished more effectively when the arc occurs. After the electric energy meter 2 completes the disconnection and arc extinguishing work, the electric energy meter 2 will continue to move up. At this time, the rack 13 is disengaged from the lower gear 33, and the rolling element 17 moves to the stop bar 18, thereby overcoming the elastic force of the first spring 15 to push the rack 13, so that the rack 13 moves to a state of meshing with the driving gear 24, and the driving gear 24 drives the switching gear 22 to rotate in the opposite direction, so that the protective cover 21 is rotated and opened through the switching shaft 20, so that the power connection structure is exposed, which is convenient for maintenance and management.

[0053] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
