Embodiment 1

[0027] Basic as attached figure 1 Shown: a reactive power compensation system, including a cabinet 10 and several power modules 20;

[0028] Several power modules 20 are installed in the cabinet 10, and the cabinet 10 is provided with a baffle 30 separating five power modules 20, and the baffle 30 divides the internal space of the cabinet 10 into 5 independent Heat dissipation space: The heat dissipation space and the mechanism are sealed, because in the specific application process, silicone oil has a certain degree of water absorption. If it is not sealed, the silicone oil will absorb water in the air, which will affect the insulation of the silicone oil.

[0029] The bottom of the cabinet 10 is provided with a through hole 11 corresponding to the cooling space;

[0030] A base 40 is provided below the cabinet 10 , and the base 40 is bonded and fixed to the cabinet 10 . There is a gap between the base 40 and the cabinet 10 . This gap is used to install the bellows 50 ment...

Embodiment 2

[0036] Compared with Embodiment 1, the only difference is that the telescopic member includes a cylinder liner and a piston that slides and seals with the cylinder liner, the cylinder liner is filled with carbon disulfide solution, the cylinder liner is fixed on the base 40, and the piston sealing plate is fixedly connected. The side of the cabinet 10 is provided with a cooling fan, and the cooling fan and the cabinet 10 are fixed by bolts.

[0037] This design is because the boiling point of carbon disulfide is 48 degrees Celsius, which allows the piston to move upward at a lower temperature. The heat dissipation effect of the cabinet 10 itself is improved by arranging a fan.

Abstract

The invention belongs to the technical field of reactive compensation. Aiming at the technical problem that an existing reactive compensation system cannot carry out targeted heat dissipation on a power module, the invention provides a reactive compensation system with good heat dissipation pertinence, which comprises a cabinet and a plurality of power modules. The plurality of power modules are all installed in the cabinet; baffles for separating the plurality of power modules are arranged in the cabinet; the baffles divide an internal space of the cabinet into a plurality of independent heatdissipation spaces by taking the power module as the unit; through holes correspondingly communicated with the heat dissipation spaces are formed at the bottom of the cabinet; a base is arranged below the cabinet; the base is fixedly connected with the cabinet; bellows full filled with silicone oil are arranged between the base and the through holes; sealing plates for sealing the bellows are arranged at the lower ends of the bellows; the bellows are respectively communicated with the heat dissipation spaces through the through holes; telescopic parts which are expanded when encountering heatare arranged below the sealing plates; one ends of the telescopic parts are connected with the base; the other ends of the telescopic parts are connected with the sealing plates; and the heat dissipation spaces, the bellows and the telescopic parts correspond one to one.

Description

technical field [0001] The invention relates to the technical field of reactive power compensation, in particular to a reactive power compensation system. Background technique [0002] The existing reactive power compensation system generally adopts air cooling or water cooling. From a heat dissipation point of view, water cooling is ideal. However, the water circulation system has high technological requirements, complicated installation, heavy maintenance workload, and once water leaks, it will bring safety hazards. Therefore, if you can use air cooling to solve the problem, don't use water cooling. The use of water cooling must solve the two major problems of the purity of the cooling water and the reliability and corrosion of the system during long-term operation. In short, the development and selection of new high-efficiency heat dissipation technology to cool power electronic devices is an important measure to ensure the reliability of the device and reduce the size...
