Description

Technical Field

[0001] This utility model relates to the field of converter technology, specifically to an energy storage converter with a lightning protection module. Background Technology

[0002] A converter is an electrical device that changes the voltage, frequency, number of phases, and other electrical quantities or characteristics of a power supply system. In practical applications, some situations require converting AC power to DC power, which is the function of a rectifier circuit. In other situations, it is necessary to convert DC power to AC power; this process, the reverse of rectification, is called an inverter circuit. Under certain conditions, a thyristor circuit can function as both a rectifier circuit and an inverter circuit; such a device is called a converter.

[0003] Since these systems are usually installed outdoors or in open areas, they are susceptible to extreme weather such as lightning strikes, storms, etc. Therefore, special lightning protection is required to ensure the safety and reliability of the system. For this purpose, an energy storage converter with a lightning protection module is provided. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an energy storage converter with a lightning protection module. The lightning protector works in conjunction with the grounding wire to absorb the lightning strike energy when a lightning strike occurs, and discharge it through the external grounding system via the grounding wire. At the same time, the surge protector works to reduce the possibility of damage to other components inside the enclosure when the lightning protector generates arcing.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An energy storage converter with a lightning protection module includes:

[0008] The converter housing serves as the connecting base, and a connecting seat is connected to the outside of the converter housing.

[0009] The surge protection assembly is connected to the converter housing and includes a surge protector connected to the inside of the converter housing and a surge protector located inside the converter housing. The surge protector is connected to the external grounding system through a grounding wire.

[0010] A movable ventilation component is attached to the inverter housing to provide auxiliary ventilation and heat dissipation inside the inverter housing.

[0011] As a preferred embodiment of the energy storage converter with lightning protection module described in this utility model, the converter housing has two sets of sliding seats symmetrically connected on the outside, and the top of the converter housing is provided with a cover plate, on which multiple sets of ventilation openings are opened.

[0012] As a preferred embodiment of the energy storage converter with lightning protection module described in this utility model, the movable ventilation component includes a drive motor connected to the outside of the connecting seat, a lead screw connected to the output end of the drive motor, and a bracket slidably connected to the converter housing. An exhaust fan is connected to the top of the bracket, and the exhaust fan vent is positioned above the ventilation opening.

[0013] As a preferred embodiment of the energy storage converter with lightning protection module described in this utility model, the bracket has a threaded seat connected to the outside of the bracket and engaged with the lead screw, and a sliding groove is provided on the inside of the bracket to engage with the sliding seat.

[0014] As a preferred embodiment of the energy storage converter with lightning protection module described in this utility model, the converter housing is provided with a driven ventilation assembly, which includes a drive pulley connected to the outside of the lead screw and a ventilation fan connected to the inside of the converter housing and moving synchronously with the drive pulley.

[0015] As a preferred embodiment of the energy storage converter with lightning protection module described in this utility model, a transmission belt is sleeved on the active pulley, the other end of the transmission belt is connected to the driven pulley, the driven pulley is connected to the main shaft of the ventilation fan, and drives the ventilation fan to operate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. When lightning strikes, the surge protector works in conjunction with the grounding wire to absorb the lightning impulse energy and discharge it through the external grounding system. At the same time, the surge protector works to reduce the possibility of damage to other components inside the enclosure when the surge protector generates arcing.

[0018] 2. The exhaust fan provides auxiliary ventilation and heat dissipation inside the converter housing. The drive motor rotates the lead screw, causing the bracket to slide along the top of the converter housing. This changes the position of the exhaust fan, achieving uniform ventilation inside the converter housing. The active pulley moves synchronously with the lead screw, thereby driving the ventilation fan connected to the driven pulley. While the exhaust fan is working, the ventilation fan assists in improving heat dissipation efficiency and effect. Attached Figure Description
