[0045] Such as figure 1 , 2 , 3, a waterless cooling energy saving and environmental protection high-power rectification system, including transformer strong oil circulation cooling main system and rectification internal circulation cooling subsystem;

[0046] The transformer strong oil circulation cooling main system includes a transformer body 16, a strong oil circulation cooler 21, a strong oil cooling circulation pump 24, a strong oil inlet pipe 22 and a strong oil outlet pipe 23; The oil inlet 14 of the strong oil circulation cooler matched with the liquid pipe 22 and the oil outlet 17 of the strong oil circulation cooler matched with the strong oil outlet pipe 23; one end of the strong oil inlet pipe 22 is connected with the strong oil circulation cooler 21 , the other end is connected with the oil inlet 14 of the strong oil circulation cooler, one end of the strong oil outlet pipe 23 is connected with the strong oil cooling circulation pump 24, and the other end is con...

Embodiment 3

[0057] Such as Figure 4 , 5 As shown, the difference between this embodiment and embodiment 2 is:

[0058] There is a relatively large liquid pipe joint on the liquid inlet pipe as the main joint of the general liquid inlet pipe. Arranged on the pipe wall of the liquid inlet pipe, as a branch joint of the liquid pipe, it is correspondingly connected to the liquid pipe joint of the liquid outlet pipe. Similarly, a relatively large main liquid pipe joint is provided on the liquid outlet pipe And the branch joint of the liquid pipe arranged on the pipe wall of the liquid outlet main pipe collects the liquid pipe branch joint on the liquid inlet main pipe, and then sends the cooling liquid with heat into the cooling radiator for circulation and cooling.

[0059] The working principle of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses a water-free cooling energy-saving and environmentally-friendly high-power rectification system, which belongs to the technical field of transformer equipment cooling, and comprises a transformer forced oil circulation cooling main system and a rectification internal circulation cooling subsystem, wherein the transformer forced oil circulation cooling main system comprisesa transformer body, a forced oil circulation cooler, a forced oil cooling circulation pump, a forced oil inlet pipe and a forced oil outlet pipe; and a cooling radiator is arranged in the transformerbody and radiates heat of the rectification internal circulation cooling subsystem into oil of the transformer body, and the oil in the transformer body is cooled by means of the transformer forced oil circulation cooling main system. The water-free cooling energy-saving and environmentally-friendly high-power rectification system achieves the effect of fluid double alternating cooling by adoptingthe rectification internal circulation cooling subsystem and the transformer forced oil circulation cooling main system, occupies small space, is small in size, saves energy, is environmentally friendly, eliminates the influence of water scale, reduces the auxiliary power consumption, eliminates water cooling in the rectifier portion, can reduce the failure rate, and makes the whole machine saferand more reliable in operation.

Description

technical field [0001] The invention belongs to the technical field of transformer equipment cooling, and in particular relates to a waterless cooling energy-saving and environment-friendly high-power rectification system. Background technique [0002] The electronic components in the rectifier cabinet will generate a large number of heat sources during the working process. Therefore, in the production of the rectifier cabinet, there are many capillary pipes in the electronic components, with water channels inside and radiators outside. Currently, there are three commonly used cooling methods for rectifiers: natural cooling, fan cooling, and water cooling. Natural cooling and heat dissipation: the ambient air temperature is not higher than 40°C, and the wind speed of natural air convection is not greater than 0.5m / s; the effect of natural cooling and heat dissipation is poor, and it is difficult to reduce the junction temperature of the device to the allowable range. The rad...
