[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figures 1-4 As shown, a surge protection device for an ultra-high frequency power supply includes: a surge protector 1; and a protective mechanism 2. The protective mechanism 2 includes a protective frame 21 disposed on the surface of the surge protector 1. A rubber plate 22 is fixedly disposed on the inner wall of the protective frame 21. A perforated block 24 is fixedly connected to the front end of the rubber plate 22. A blocking frame 25 is slidably connected to the inner wall of the perforated block 24. A spring 26 is fixedly connected to the opposite end of the blocking frame 25 and the perforated block 24. A transparent plate 23 is slidably connected to the inner wall of the protective frame 21. Both the perforated block 24 and the blocking frame 25 are rubber components.

[0024] When surge protection is needed for ultra-high frequency power supply equipment such as a small photovoltaic inverter, the protective frame 21 is installed on the wall near the small photovoltaic inverter through bolts, and the rubber plate 22 is installed in the protective frame 21 through bolts. At this time, the surge protector 1 suitable for the voltage of the small photovoltaic inverter is placed at the hollow block 24, the elastic force of the spring 26 pushes the blocking frame 25 to move, thereby blocking the surge protector 1, and the surge protector 1 is installed in front of the rubber plate 22. One end of the corresponding wire is connected to the corresponding position of the small photovoltaic inverter, the other end of the corresponding wire is inserted through the reserved hole at the bottom of the protective frame 21 and is installed at the bottom of the surge protector 1, and the length of the corresponding wire is as short as possible to reduce the influence of wire inductance and resistance on the protection effect. Long lines may cause reflection and oscillation of surge current during transmission, reducing the effectiveness of the protection device. Reasonably arrange the wiring method to avoid mutual interference between different lines. One end of the grounding line is inserted through the reserved hole at the bottom of the protective frame 21 and is installed at the bottom of the surge protector 1, and the other end of the grounding line is installed at the corresponding position, so that the grounding resistance meets the relevant standard requirements. Good grounding is the key to ensure that the protection device can quickly introduce the surge current into the ground, and poor grounding may cause the surge current to be unable to effectively discharge, thereby affecting the protection effect.

[0025] When a surge occurs, a large current will be generated, and the surge protector 1 has a low impedance characteristic, which can provide a preferential discharge path for the surge current. The surge current will flow into the ground through the surge protector 1, and will not pass through the small photovoltaic inverter, thereby avoiding excessive current from causing thermal damage and electrical damage to the small photovoltaic inverter.

[0026] The surge protector 1 can also be reasonably matched with the circuit of the small photovoltaic inverter to share part of the current load during normal operation. When a temporary overload occurs in the small photovoltaic inverter, the surge protector 1 can help the small photovoltaic inverter withstand a certain current pressure to prevent the small photovoltaic inverter from being damaged due to overload.

[0027] As shown in Figure 3 The front end of the rubber plate 22 is slidingly connected with a fixed frame 27, and the surface of the fixed frame 27 is sequentially clamped to the inner wall of the blocking frame 25 and one side of the hollow block 24.

[0030] The transparent plate 23 is pushed upwards, the top of the limiting plate 212 abuts against the inner top wall of the guard frame 21, at this time, the iron block 28 is pushed, the iron block 28 is clamped into the transparent plate 23 and is attracted into the magnetic block 29, the transparent plate 23 stably blocks the opening at the front end of the guard frame 21, and then external force touches the surface of the surge protection device 1.

[0031] When the guard frame 21 is subjected to external force, the guard frame 21 transmits the external force to the rubber plate 22, the rubber plate 22 has viscoelasticity, and when subjected to external force, it will deform, the external force causes relative movement and internal friction between rubber molecular chains, converts mechanical energy into heat energy and dissipates, thereby playing a dispersion and buffering effect, and then dispersing the external force transmitted to the surge protection device 1.

[0032] As shown in the figure, Figure 4 The inner wall lower end of the guard frame 21 is fixedly connected with a support plate 211, and the bottom of the rubber plate 22 abuts against the top of the support plate 211.

[0033] In use, the guard frame 21 is installed on the wall surface near the photovoltaic small inverter by bolts, the rubber plate 22 is installed into the guard frame 21 by bolts, the bottom of the rubber plate 22 stably abuts against the top of the support plate 211, at this time, the surge protection device 1 with a voltage suitable for the photovoltaic small inverter is placed at the hollow block 24, the elastic force of the spring 26 pushes the blocking frame 25 to move, thereby blocking the surge protection device 1, the fixed frame 27 is pushed, the surface of the fixed frame 27 is clamped into the blocking frame 25 and one of the hollow blocks 24 in sequence, the surge protection device 1 is stably installed at the front end of the rubber plate 22, the transparent plate 23 is pushed upwards, the top of the limiting plate 212 abuts against the inner top wall of the guard frame 21, at this time, the iron block 28 is pushed, the iron block 28 is clamped into the transparent plate 23 and is attracted into the magnetic block 29, the transparent plate 23 stably blocks the opening at the front end of the guard frame 21.
