DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1~Figure 5 As shown, this embodiment proposes an outdoor high-voltage combined transformer, including

[0031] A base 1 and a shell 2, wherein the shell 2 is arranged outside the base 1;

[0032] A pair of bottom grooves 3, the bottom grooves 3 are formed in the surface of the base 1;

[0033] A current transformer 4, a voltage transformer 5 and a shock absorbing assembly 6, wherein the shock absorbing assembly 6 is arranged inside the bottom groove 3;

[0034] A heat dissipation and dustproof component 7, which is arranged inside the housing 2;

[0035] The shock absorbing assembly 6 includes a pair of bottom rods 6-1, which are arranged in the bottom groove 3. The bottom rod 6-1 is slidably connected to the bottom plate 6-2 on the outside, and the first spring 6-3 is sleeved on the outside of the bottom rod 6-1. A pair of round rods 6-4 are arranged on both end surfaces of the bottom plate 6-2. The round rod 6-4 is slidably connected to the moving block 6-5 on the outside. The upper end of the moving block 6-5 is rotatably connected to the support rod 6-6 through a pin shaft. The upper end of the support rod 6-6 is rotatably connected to the shock absorbing seat 6-7 through a pin shaft. The round rod 6-4 is sleeved on the outside with a second spring 6-8. A hydraulic buffer rod 6-9 is arranged on the top of the bottom groove 3. The shock absorbing seat 6-7 is fixedly connected to the current transformer 4 and the voltage transformer 5.

[0036] In this embodiment, in order to achieve the shock absorption effect of the current transformer 4 and the voltage transformer 5 during operation, a shock absorption assembly 6 is designed. Two bottom rods 6-1 are installed in the two bottom grooves 3. The outside of the bottom rod 6-1 is slidably connected to a movable bottom plate 6-2. The two ends of the bottom rod 6-1 are sleeved and connected with a first spring 6-3. The first spring 6-3 is supported between the side surface of the bottom groove 3 and the bottom plate 6-2, so that the bottom plate 6-2 can move left and right to achieve a buffering effect. Round rods 6-4 are arranged on both sides of the bottom plate 6-2, and a moving block 6-5 is slidably connected to the round rod 6-4. The moving block 6-5 is also connected to a support rod 6-6, and the top of the support rod 6-6 is connected to a shock-absorbing seat 6-7. The shock-absorbing seat 6-7 can move up and down through the moving block 6-5 and the support rod 6-6. The moving block 6-5 slides on the round rod 6-4, and a second spring 6-8 is mounted on the round rod 6-4. The bottom rod 6-1 and the round rod 6-4 buffer the longitudinal and lateral vibrations respectively to achieve effective buffering, and a hydraulic buffer with the output end facing downward is arranged on the top of the bottom groove 3. When the shock-absorbing seat 6-7 sinks and resets, it cooperates with the hydraulic buffer to buffer the falling back force.

[0037] Furthermore, the heat dissipation and dustproof component 7 includes an air inlet 7-1, which is opened on both side surfaces of the bottom groove 3, and a filter screen 7-2 is installed in the air inlet 7-1. An air collecting hood 7-3 is arranged at the top of the outer shell 2, and a plurality of base frames 7-4 are arranged at the bottom of the air collecting hood 7-3. An air collecting port 7-5 is opened at the bottom of the air collecting hood 7-3, and the air collecting port 7-5 is located directly above the base frame 7-4. A plurality of heat absorbing fins 7-6 are installed in the base frame 7-4. A pair of circular openings 7-7 are opened at the top of the outer shell 2, and a cooling fan 7-8 is installed in the circular opening 7-7. A shielding cover 7-9 is arranged at the top of the outer shell 2.

[0038] In this embodiment, in order to achieve efficient heat dissipation inside the shell 2, a heat dissipation and dustproof component 7 is designed. Air inlets 7-1 are opened on both sides of the bottom groove 3, and a filter screen 7-2 is installed in the air inlet 7-1. Air can enter the bottom groove 3 through the air inlet 7-1. A circular opening 7-7 is opened on the top of the shell 2 and a heat dissipation fan 7-8 is installed. The heat dissipation fan 7-8 can blow air upward so that gas enters at the air inlet 7-1 by suction, continuously replaces the hot air in the shell 2, and accelerates the heat dissipation. A base frame 7-4 is provided at the bottom of the air collecting hood 7-3, and heat absorbing fins 7-6 are installed in the base frame 7-4. Heat can be concentrated in the heat absorbing fins 7-6 to accelerate the concentrated discharge of heat.

[0039] Furthermore, the base frame 7 - 4 is connected to the two ends of the bottom of the gas collecting cover 7 - 3 and between the current transformer 4 and the voltage transformer 5 .

[0040] In this embodiment, heat can be absorbed more quickly by the heat-absorbing fins 7 - 6 through uniform distribution at multiple positions, thereby enhancing the heat dissipation effect.

[0041] Furthermore, a plurality of long ventilation holes 8 are evenly formed on the surface of the shock absorbing seat 6-7.

[0042] In this embodiment, a plurality of long ventilation holes 8 are formed on the surface of the shock absorbing seat 6-7 so that the external air can pass through the shock absorbing seat 6-7 when entering, thereby increasing the gas flow range and enhancing the heat dissipation effect.

[0043] Furthermore, the base frame 7-4 is a door-shaped structure with two sides open.

[0044] In this embodiment, the door-shaped open structure allows all the heat dissipation fins to be exposed to the outside, ensuring that they can fully absorb heat.

[0045] Furthermore, a window 9 is provided on the surface of the shell 2, and a door cover 10 is rotatably connected to the surface of the shell 2 via a pin shaft.

[0046] In this embodiment, the window 9 and the door cover 10 can be opened at any time for internal inspection or maintenance.

[0047] When needed, the current transformer 4 and the voltage transformer 5 are installed on two shock-absorbing seats 6-7 respectively. During operation, the cooling fan 7-8 on the top is kept running, and the external air is drawn into the bottom tank 3 through the air inlet 7-1. When entering, the dust is filtered out by the filter 7-2, and the heat-absorbing fins 7-6 absorb the heat. The gas flows upward and the hot air is discharged outward at the top. When vibration occurs, the bottom bottom plate 6-2 will slide longitudinally on the bottom rod 6-1, and cooperate with the first spring 6-3 to perform shock absorption and buffering. At the same time, the bottom of the shock-absorbing seat 6-7 moves on the round rod 6-4 through the support rod 6-6 and the moving block 6-5, and cooperates with the second spring 6-8 to perform shock absorption and buffering. Each time vibration occurs, the shock-absorbing seat 6-7 will be restored to a stable state through the hydraulic buffer rod 6-9, so that the current transformer 4 and the voltage transformer 5 can operate stably.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
