Description

Technical Field

[0001] The present invention relates to the technical field of power supply systems, and in particular to a distributed energy supply output system of an energy storage power station. Background Art

[0002] Energy storage power stations refer to facilities that use batteries, supercapacitors and other devices to store electrical energy to solve the problem of energy supply and demand imbalance and ensure the stable operation of the power grid. Its main function is to store and redistribute excess electricity when the power grid capacity is limited, and at the same time improve the efficiency of electrical energy utilization. Common energy storage power stations use electrochemical batteries, such as ternary lithium and lithium iron phosphate batteries, to store electrical energy. Multiple battery cluster units are usually set up in an energy storage power station, and the battery cluster unit is composed of several battery cells. When supplying power to the outside, in traditional technology, the battery cluster units are connected in parallel or in series and then discharged through the inverter device; this method has the following defects: if all the battery cluster units in the energy storage power station are connected in parallel or in series and supply power to the outside at the same time, the energy storage power station cannot be charged at this time. Due to the unidirectional electrochemical properties of the battery, it cannot be charged when discharging; and the battery cluster unit is divided into two or more parts, one part is discharged and the other part is charged.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 10 The present invention provides a technical solution: a distributed energy supply output system of an energy storage power station, such as Figure 1 As shown in, it includes a charging management module, a distributed control relay, a battery cluster unit, a switching device and an inverter module.

[0031] The switching device includes an insulating fixed main seat 1, an upper conductive plate group 2 and a lower conductive plate group 3. The upper conductive plate group 2 and the lower conductive plate group 3 are both embedded and fixed on the insulating fixed main seat 1. The upper conductive plate group 2 is connected to one group of battery cluster unit circuits, and the lower conductive plate group 3 is connected to the other group of battery cluster unit circuits.

[0032] The ends of the upper conductive plate group 2 and the lower conductive plate group 3 are respectively fixed with sliding contact platforms 4, and the outer limit sliding of the insulating fixed main seat 1 is provided with an insulating lifting body 5, and the surface of the insulating lifting body 5 is provided with a conductive touch plate 6, and the conductive touch plate 6 is in conductive contact with the sliding contact platform 4; when the insulating lifting body 5 is lifted and slid, the conductive touch plate 6 can switch between the sliding contact platform 4 corresponding to the upper conductive plate group 2 and the sliding contact platform 4 corresponding to the lower conductive plate group 3, and the spacing between the two groups of sliding contact platforms 4 is smaller than the width of the conductive touch plate 6, so that the conductive touch plate 6 can be switched between the sliding contact platform 4 corresponding to the upper conductive plate group 2 and the sliding contact platform 4 corresponding to the lower conductive plate group 3. The spacing between the two groups of sliding contact platforms 4 is smaller than the width of the conductive touch plate 6, so that the conductive touch plate 6 can be switched between the two groups of sliding contact platforms 4. When the moving contact platform 4 is between them, it can be connected with two groups of sliding contact platforms 4 at the same time. An associated vertical groove 7 is opened in the insulating fixed main seat 1. A synchronous T-shaped plate 8 is fixedly set on the surface of the insulating lifting body 5. The synchronous T-shaped plate 8 is inserted through the associated vertical groove 7. A control screw 9 is rotatably set in the associated vertical groove 7.

When the control screw 9 rotates, the insulating lifting body 5 can be driven to move up and down through the cooperation of the control screw 9 and the synchronous T-shaped plate 8. The insulating fixed main seat 1 and the insulating lifting body 5 are both made of insulating materials, such as plastic.

[0033] like Figure 4 As shown in the figure, a main seat inner groove 101 is opened in the insulating fixed main seat 1, and the synchronous T-shaped plate 8 is located inside the main seat inner groove 101. The upper and lower surfaces of the synchronous T-shaped plate 8 are symmetrically provided with corrugated airbags 102, and the corrugated airbags 102 are closed in cooperation with the inner wall surface of the main seat inner groove 101. The bottom and top surfaces of the main seat inner groove 101 are respectively provided with air intake filter covers 103, and the air intake filter covers 103 are correspondingly connected with the corrugated airbags 102. A gas filter membrane 104 is provided in the air intake filter cover 103, and a one-way air intake valve 105 is embedded and fixed in the air intake filter cover 103. The one-way air intake valve 105 allows the external air flow to flow unidirectionally to the inside of the corrugated airbag 102.

[0034] An intra-plate air path 107 is opened inside the synchronous T-shaped plate 8, and a one-way air outlet valve 106 is fixedly arranged on the surface of the synchronous T-shaped plate 8. The corrugated airbag 102 is connected to the intra-plate air path 107 through the one-way air outlet valve 106. The one-way air outlet valve 106 allows the gas in the corrugated airbag 102 to flow unidirectionally into the intra-plate air path 107.

[0035] An output nozzle 109 is provided inside the conductive touch plate 6, and an air guide groove 110 is provided on the surface of the conductive touch plate 6 facing the sliding contact platform 4. The output nozzle 109 is connected to the air guide groove 110, and a connecting air pipe 108 is provided outside the output nozzle 109, and the other end of the connecting air pipe 108 is connected to the air path 107 inside the plate.

[0036] like Fig.10As shown in , a limited slot cavity 501 is provided in the insulating lifting body 5, and a push end block 502 is limitedly provided in the limited slot cavity 501, and the push end block 502 is fixedly connected with the conductive touch plate 6, and a power supply output board 503 is fixedly provided on the surface of the insulating lifting body 5, and a braided conductive belt 504 is provided between the power supply output board 503 and the pushing end block 502 for conductive connection, and the switching device outputs to the inverter module through the power supply output board 503. A pressure spring 505 is provided on one side of the pushing end block 502, and a control back plate 506 is provided at one end of the pressure spring 505. The pressure spring 505 applies elastic pressure to the pushing end block 502, so that the conductive touch plate 6 is elastically pressed on the surface of the sliding contact platform 4, and the outer cover of the control back plate 506 is provided with a back plate positioning cover 507. A fixed arm 508 is fixedly arranged on the surface of the back plate positioning cover 507, and the fixed arm 508 is fixedly installed on the insulating lifting body 5. A multi-stage spring clip 509 is arranged between the control back plate 506 and the back plate positioning cover 507, and the multi-stage spring clip 509 applies an elastic thrust to the control back plate 506 in the direction of the pressure spring 505.

[0037] The elastic thrust provided by the multi-stage spring clip 509 is greater than the elastic thrust provided by the pressure spring 505. A wear limit column 510 is fixedly provided on the surface of the control back plate 506 facing the pressure spring 505. A friction track bar 511 is fixedly provided on the insulating fixed main seat 1. The wear limit column 510 is in friction contact with the friction track bar 511. When the insulating lifting body 5 moves up and down, the wear limit column 510 slides frictionally on the surface of the friction track bar 511. The wear rate between the conductive contact plate 6 and the sliding contact platform 4 is the same as the wear rate between the wear limit column 510 and the friction track bar 511. The wear rate between the wear limit column 510 and the friction track bar 511 can be controlled by adjusting the surface finish of the friction track bar 511 or the hardness of the wear limit column 510.

[0038] A fixed frame 901 is fixedly arranged on the surface of the insulating fixed main seat 1 , and a motor module 902 is fixedly arranged in the fixed frame 901 . The motor module 902 is used for driving the control screw 9 to rotate.

[0039] When the distributed energy supply output system of the present invention is working, Figure 1 As shown in the example, there are two groups of battery cluster units in the energy storage power station, and combined with Figure 2 In the switching device, the upper conductive plate group 2 and the lower conductive plate group 3 both have positive and negative poles, the upper conductive plate group 2 is connected to the positive and negative poles of one group of battery cluster units, and the lower conductive plate group 3 is connected to the positive and negative poles of another group of battery cluster units.

[0040] like Figure 2 and Figure 4As shown in , when the insulating lifting body 5 is at the upper side, the upper conductive plate group 2 is connected in turn through the sliding contact platform 4, the conductive touch plate 6, the push end block 502, the braided conductive belt 504 and the power output board 503, and the power output board 503 is connected to the input end of the inverter module for power supply, and the inverter module outputs AC power to the power grid for external discharge; at this time, the battery cluster unit connected to the upper conductive plate group 2 discharges externally; Figure 4 and Figure 5 As shown in , when the battery cluster unit connected to the upper conductive plate group 2 is about to run out of power, the motor module 902 drives the control screw 9 to rotate and switch. When the control screw 9 rotates, the synchronous T-shaped plate 8, the insulating lifting body 5 and the conductive touch plate 6 are synchronously driven to move downward. During the downward movement, the conductive touch plate 6 will gradually make contact with the sliding contact platform 4 at the lower position, but at this time, the conductive touch plate 6 is still powered on and connected to the sliding contact platform 4 corresponding to the upper conductive plate group 2. Therefore, in the current state, the two battery cluster units are in a temporary parallel state. As the conductive touch plate 6 continues to move downward, the conductive touch plate 6 completely separates from the sliding contact platform 4 at the upper position and makes power contact with the sliding contact platform 4 at the lower position. At this time, the battery cluster unit connected to the upper conductive plate group 2 is completely disconnected, and the battery cluster unit connected to the lower conductive plate group 3 is discharged to the outside, and there will be no power failure during the above-mentioned battery cluster unit switching process.

[0041] When there is external electrical energy that needs to be stored, after being processed by the charging management module, the distributed control relay is used to control the battery cluster units connected to the upper conductive plate group 2 to charge, while the battery cluster units connected to the lower conductive plate group 3 discharge to the outside.

[0042] In the above process, the conduction touch plate 6 and the sliding contact platform 4 move relative to each other, resulting in an increase in resistance between the two, which increases the heat generated between the conduction touch plate 6 and the sliding contact platform 4. At the same time, since the synchronous T-shaped plate 8 moves with it, when the synchronous T-shaped plate 8 moves downward, the corrugated airbag 102 below the synchronous T-shaped plate 8 will be squeezed, and the gas enters the plate internal gas path 107 through the one-way air outlet valve 106, and finally sprays out through the output nozzle 109 to dissipate heat between the conduction touch plate 6 and the sliding contact platform 4. The corrugated airbag 102 above the synchronous T-shaped plate 8 is in a negative pressure suction state, and the outside air is sucked in through the one-way air inlet valve 105. Through the above structure, the upward and downward movement of the synchronous T-shaped plate 8 generates positive pressure gas, so that the output nozzle 109 always sprays positive pressure, which can blow away the particle dust between the conduction touch plate 6 and the sliding contact platform 4. The particle dust may come from the wear between the conduction touch plate 6 and the sliding contact platform 4, or from the outside.

[0043] like Fig.10As shown in the figure, the relative movement between the conductive touch plate 6 and the sliding contact platform 4 will cause gradual wear between the two. Assuming that the control back plate 506 is in a fixed state, since the conductive touch plate 6 provides an extrusion elastic force through the pressure spring 505, when the conductive touch plate 6 and the sliding contact platform 4 are gradually worn, the pressure spring 505 will be in a gradually released state. As the length of the pressure spring 505 is extended, the contact pressure between the conductive touch plate 6 and the sliding contact platform 4 is reduced. In the present application, through structural settings, the wear speed between the wear limit column 510 and the friction track bar 511 is consistent with the wear speed between the conductive touch plate 6 and the sliding contact platform 4. When the conductive touch plate 6 and the sliding contact platform 4 are worn, the wear limit column 510 and the friction track bar 511 are worn at the same time. Since the elastic force of the multi-stage spring sheet 509 is greater than the elastic force of the pressure spring 505, the control back plate 506 will move toward the pressure spring 505 as the wear between the wear limit column 510 and the friction track bar 511 wears, and the compression degree of the pressure spring 505 is maintained, so that the elastic force provided by the pressure spring 505 remains unchanged within the error range, ensuring that the contact pressure between the conductive touch plate 6 and the sliding contact platform 4 will not decrease with wear, thereby improving the performance stability of the device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
