[0021] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the utility model provides an anti-condensation high-voltage cabinet busbar chamber, as Figures 1-5 shown. The anti-condensation high-voltage cabinet busbar chamber includes: a busbar chamber body 1; an arc-shaped top cover 2 fixedly installed on the top of the busbar chamber body 1; a condensation sensor 3 fixedly installed on one inner wall of the busbar chamber body 1, and the condensation sensor 3 is used to monitor the temperature and humidity inside the busbar chamber body 1; a plate heater 4 fixedly installed on the bottom inner wall of the busbar chamber body 1, and the plate heater 4 is used to heat the outer frame of the busbar chamber body 1; a dehumidification mechanism 5 arranged inside the busbar chamber body 1, and the dehumidification mechanism 5 is used to dehumidify the inside of the busbar chamber body 1; a filtering mechanism 6 assembled on the dehumidification mechanism 5, and the filtering mechanism 6 is used to filter the air used by the dehumidification mechanism 5.

[0023] In this embodiment, during the operation of the busbar chamber body 1, the arc-shaped top cover 2 is coated with anti-condensation paint. Through the arc-shaped top cover 2, some condensed water droplets generated at the top of the busbar chamber body 1 can be well diverted (the arc-shaped top cover 2 is connected to the busbar chamber body 1). The condensation sensor 3 can monitor the temperature and humidity inside the busbar chamber body 1. When it is detected that the temperature inside the busbar chamber body 1 is too low, the condensation sensor 3 sends a signal to the controller. The controller receives and identifies the signal and starts the plate heater 4 (a controller is provided on the busbar chamber body 1, and the control operation is carried out through the controller. This is the prior art and will not be elaborated here). The plate heater 4 heats the outer frame of the busbar chamber body 1, thereby preventing water vapor from condensing into water droplets on the outer frame of the busbar chamber body 1. At the same time, when the condensation sensor 3 detects that the humidity inside the busbar chamber body 1 is too high, the controller will start the dehumidification mechanism 5 to accelerate the replacement of the moisture inside the busbar chamber body 1, thereby dehumidifying the inside of the busbar chamber body 1, reducing the occurrence of condensation inside the busbar chamber body 1. During the use of the entire busbar chamber body 1, the generation of condensation can be well avoided, and the occurrence of partial discharge and corrosion can be avoided, thereby reducing the impact on the high-voltage switchgear and improving the safety of the high-voltage switchgear during use. At the same time, when using the dehumidification mechanism 5, under the action of the filtering mechanism 6, the impurities in the air can be well filtered to prevent impurities from entering the busbar chamber body 1.

[0025] In this embodiment, when using the dehumidification mechanism 5, the controller starts the blower 501, the drying box 503 removes the moisture in the air, and the dried air enters the busbar chamber body 1 through the dehumidification pipe 505, so as to accelerate the replacement of the humid air inside, thereby playing a role in dehumidifying the busbar chamber body 1, and thus reducing the occurrence of condensation in the busbar chamber body 1.

[0026] In a further preferred embodiment of the present utility model, the filtering mechanism 6 includes: a mounting shell 601 arranged in the arc-shaped top cover 2; two filter frames 602 assembled in the mounting shell 601, a positioning block is fixedly installed in the mounting shell 601 for positioning the filter frames 602, and the filter frames 602 are in contact with the positioning block; two sealing covers 603 threadedly installed on the mounting shell 601, and the two sealing covers 603 are respectively in contact with the two filter frames 602; two connecting heads 604 respectively fixedly installed on the two sealing covers 603, one of the connecting heads 604 is communicated with the air inlet pipe 502, and the other connecting head 604 extends to the outside of the arc-shaped top cover 2.

[0027] In this embodiment, when using the dehumidification mechanism 5, under the action of the two filter frames 602, impurities in the air can be filtered well, and impurities can be prevented from entering the busbar chamber body 1, and under the action of the sealing covers 603, it is convenient to disassemble and clean the filter frames 602.

[0029] In this embodiment, the insulator 7 is used to fix the branch copper bars in the busbar chamber body 1, and the contact box 8 can be used to connect the static contact in the contact box 8 and one end of the branch copper bar.

[0030] In a further preferred embodiment of the present utility model, a drying mechanism is provided inside the busbar chamber body 1. The drying mechanism is used to dry the inside of the busbar chamber body 1, and the drying mechanism includes: a placement frame 9 fixedly installed on the inner wall of the bottom of the busbar chamber body 1; desiccant 10 placed inside the placement frame 9, and the desiccant 10 is used to dry the inside of the busbar chamber body 1.

[0031] In this embodiment, the desiccant 10 can dry the inside of the busbar chamber body 1, thereby reducing the humidity inside the busbar chamber body 1 and reducing the generation of condensation.
