Description

Technical Field

[0001] This article belongs to the technical field of energy storage devices, and specifically relates to an energy storage device with built-in current conversion and boosting functions. Background Art

[0002] At present, the new energy energy storage current conversion and boosting integrated cabin is an integrated power equipment composed of an energy storage system, a current conversion system, and a boosting system. Its main function is to store the direct current collected from new energy sources such as solar energy and wind energy through the energy storage system, then convert it into alternating current through the current conversion system, and boost the output voltage through the boosting system, and then send it to the power grid.

[0003] The energy storage box-type substation supporting the energy storage project has also been widely used. The existing box-type substations have problems such as large equipment floor area, long construction period, and high cost. In particular, a large amount of copper bars are required for the energy storage converter to connect to the high-voltage switchgear of the transformer, further increasing the volume of the entire box-type substation and increasing the cost of the box-type substation shell. Utility Model Content

[0004] To solve the above problems, this article proposes an energy storage device with built-in current conversion and boosting functions. The energy storage device includes an energy storage battery cabinet and a cable tray. The energy storage battery cabinet is provided above the cable tray. A connection lead well is provided above the center of the cable tray. One end of the upper surface of the cable tray is provided with an energy storage battery cabinet, and the other end of the upper surface of the cable tray is provided with a high-voltage chamber. A transformer chamber is provided between the high-voltage chamber and the energy storage battery cabinet. The transformer chamber communicates with the high-voltage chamber. A heat dissipation grille is provided between the transformer chamber and the energy storage battery cabinet. A conducting busbar is horizontally provided at the bottom of the heat dissipation grille. One end of the conducting busbar is connected to the inside of the transformer chamber, and the other end of the conducting busbar is connected to the connection lead well. The connection lead well and the conducting busbar are both horizontally provided at the inner bottom of the heat dissipation grille. The connection lead well is connected to the energy storage battery cabinet through the bottom of the cable tray. The heat dissipation grille is connected to the inside of the deformation chamber through a heat pipe. The energy storage device that could only output direct current originally, or needed to use other special transformers to connect for alternating current output, realizes the direct alternating current output of the energy storage battery chamber through the built-in transformer and the high-voltage chamber, thereby reducing the equipment floor area, reducing the construction period, reducing the cost, reducing the large amount of copper bars required for the energy storage converter to connect to the high-voltage switchgear of the transformer, further reducing the volume of the entire box-type substation, and reducing the cost of the box-type substation shell.

[0005] The wiring chassis is in the shape of a rectangular frame assembly frame, and a hollow wiring cavity is provided inside the wiring chassis. A guide bar is provided inside the hollow wiring cavity, and both ends of the hollow wiring cavity are respectively connected to the energy storage battery cabinet and the connecting lead well. The upper surface of the wiring chassis is provided with an energy storage battery cabinet, a connecting busbar, a heat dissipation grille, a transformer chamber, a high-voltage chamber and a low-voltage chamber. The wiring chassis can be integrally arranged above the energy storage battery cabinet, a transformer, a high-voltage cabinet and a heat dissipation grille, so that the entire transformer equipment and the energy storage equipment are integrated, and the wiring inside the wiring chassis can also be hidden.

[0006] The energy storage battery cabinet is in the shape of a rectangular cabinet with built-in energy storage batteries. A switch cabinet is provided inside the energy storage battery cabinet, a series interface is provided on the outside of the energy storage battery cabinet, and an output interface is provided at the bottom of the energy storage battery cabinet. The energy storage battery cabinet can be conveniently connected to other energy storage devices through the series interface. The output connection is made at the bottom of the energy storage battery cabinet to achieve the effect of hiding the line.

[0007] The connecting lead well is a vertical wire outlet well. The connecting lead well is embedded in the upper surface of the wiring base. The upper and lower end surfaces of the connecting lead well are wire sockets. The wire socket at the lower end is connected to the energy storage battery cabinet through the busbar, and the wire socket at the upper end is connected to the wire busbar. Through the connecting lead well, stable wire outlet can be conveniently carried out from the upper surface of the wiring base frame, thereby facilitating the installation of the guide busbar connection and ensuring the stability of the overall wire installation.

[0008] The inner side of the transformer chamber is connected to the high-voltage chamber through an insulator, and coolers are provided above the front and rear ends of the outer side of the transformer chamber. The interior of one end of the cooler is connected to the interior of the transformer and the interior of the high-voltage chamber, and a heat pipe is horizontally provided on the outer side of the other end of the cooler. A heat dissipation grille is connected to the outer side of the heat pipe. The high-voltage chamber is a rectangular vertical cabinet room, and a low-voltage chamber is provided on the outer side of the high-voltage chamber. The low-voltage chamber is a low-voltage circuit control room, which is connected to the high-voltage chamber through the transformer chamber, so that it can be conveniently led out directly from the high-voltage chamber after the transformation is completed. Moreover, the transformer chamber and the high-voltage chamber can also be assisted by the low-voltage chamber for control, thereby improving the integrity and overall controllability of the device.

[0009] The heat dissipation grille is a longitudinally spaced grille, which is longitudinally penetrated between the energy storage battery cabinet and the transformer room. The transverse center line of the heat dissipation grille is symmetrically arranged on the front and rear sides of the connecting busbar. The heat dissipation grille can be used to conduct the high temperature inside the transformer room and the high-voltage room through the heat pipe, and can also assist in the heat dissipation of the connecting lead well and the connecting busbar. Moreover, the heat dissipation grille can separate the energy storage battery cabinet and the transformer room, thereby realizing the separation of the two high-temperature equipment, and can also achieve longitudinal separation to ensure the heat dissipation effect.

[0010] Beneficial effects:

[0011] The energy storage device, which originally could only output DC or needed to use other special transformers to connect to AC output, can achieve direct AC output in the energy storage battery room through the built-in transformer and high-voltage chamber, thereby reducing the equipment footprint, shortening the construction period, reducing costs, and reducing the need to use a large number of copper bars to connect the energy storage inverter with the high-voltage switchgear of the transformer, further reducing the size of the entire box-type substation and reducing the cost of the box-type substation shell.

[0012] The wiring chassis can be used to integrally install energy storage battery cabinets, transformers, high-voltage cabinets and heat dissipation grilles on top of it, so as to integrate the entire transformer equipment and energy storage equipment, and also to achieve hidden wiring inside the wiring chassis.

[0013] The energy storage battery cabinet can be conveniently connected to other energy storage devices through a series interface, and the output connection is made at the bottom of the energy storage battery cabinet to achieve the effect of hiding the circuit.

[0014] By connecting the lead well, the wires can be easily and stably led out from the upper surface of the wiring chassis, which can facilitate the installation of the guide busbar connection and ensure the stability of the overall installation of the wires.

[0015] By connecting the transformer chamber with the high-voltage chamber, it is possible to conveniently lead the voltage directly out from the high-voltage chamber after the voltage transformation is completed. Moreover, the transformer chamber and the high-voltage chamber can also be assisted in being controlled through the low-voltage chamber, thereby improving the integrity and overall controllability of the device.

[0016] The heat dissipation grille can be used to conduct the high temperature inside the transformer chamber and the high-voltage chamber through heat pipes, and can also assist in the heat dissipation of the connecting lead well and the connecting busbar. The heat dissipation grille can separate the energy storage battery cabinet and the transformer chamber, thereby separating the two high-temperature equipment, and can also achieve longitudinal separation to ensure the heat dissipation effect.
