Description

Technical Field

[0001] The utility model belongs to the technical field of power electronic equipment, and more specifically, relates to a high-ratio pulse discharge switch module. Background Art

[0002] As a core component in the power electronics field, high-ratio pulsed discharge switch modules play an irreplaceable role in numerous fields, including energy conversion, communications equipment, and industrial automation. Their efficient and stable operation is directly related to the performance and reliability of the entire system. Therefore, improving the efficiency of these modules has become a key research and application topic. In practical applications, these modules often suffer from low efficiency, high energy loss, and insufficient reliability. These issues arise, in part, from inefficient module design, which leads to excessive losses during the energy conversion process; and in part from limitations in the production process, which introduce errors and instabilities into the module's production.

[0003] The prior art includes a technology called "discharge switch" with publication number "CN2413370Y," which includes a housing and a discharge electrode. The housing has an air inlet on the lower cover and an air outlet on the upper cover. There is one or more air inlets or outlets. The discharge electrode is sheet-shaped and has a hole in the center, with the center of the hole aligned with the axial position of the other electrode. The housing of the utility model is ventilated, not vacuum-sealed, and is simple to manufacture. Dust is difficult to adhere to the electrode, making it less likely to cause continuous strikes, and the electrode has a long service life. The electrode is sheet-shaped, and discharge can occur at any point, so discharge is no longer dependent on a single point, resulting in stable high-voltage discharge and high reliability. Furthermore, because the electrode material does not require precious metals, the cost is low and manufacturing is easy.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0011] The front cover plate includes a front front cover plate and a front rear cover plate, and the back cover plate includes a back front cover plate and a back rear cover plate.

[0012] An indication unit is installed on the front panel of the integrated module housing.

[0013] The integrated module core control unit is arranged at the front end inside the integrated module shell.

[0014] A connecting seat is provided on the unit base plate, and a connecting seat screw hole is provided on the connecting seat. Bolts passing through the connecting seat screw hole are connected to the cooling unit screw hole on the cooling unit.

[0015] The module parallel connection piece is fixed at the rear end of the integrated module shell. Each discharge switch module unit on one side of the cooling unit is connected to the module parallel connection piece in parallel. Each discharge switch module unit on the other side of the cooling unit is connected to the module parallel connection piece in parallel.

[0016] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:

[0017] The high-ratio pulsed discharge switch module described in the present invention features the following structural design: 1. The high-ratio pulsed discharge switch module utilizes fast-response switching devices, enabling precise control of current flow and interruption in a very short time.

Furthermore, the discharge switch module and other components are housed within the integrated module housing, resulting in a high device layout density, a small overall height, and a large heat dissipation contact surface. Compared to traditional columnar capacitors, the module offers higher energy density and improved heat dissipation efficiency, further reducing volume and increasing power density. 3. The high-ratio pulsed discharge switch module ensures high energy conversion efficiency under various operating conditions. Through real-time monitoring and adjustment, the module can avoid abnormal situations such as overload and short circuit, thereby improving the overall efficiency and stability of the system. 4. The high-ratio pulse discharge switch module uses a cooling unit as a heat dissipation structure to ensure that the module can still work stably in a high-temperature environment. Through the effective heat dissipation design of the cooling unit, the temperature of the internal components of the module can be reduced, the energy loss caused by overheating can be reduced, the efficiency of energy conversion can be improved, and the power density of the module can be increased. Compared with traditional switch modules, the above solution has a 25% reduction in volume, a 33% increase in energy density, a higher degree of integration, easier assembly, reduced costs, and reduced weight.

The above structure proposes an improved technical solution to the deficiencies in the existing technology. When setting the structure, the solution adopted is: 1.
