Muhimmin mutanen da suke da su shine load switches da fuses, da ke da muhimmanci da suke da su shine simple structure, small size, low cost, improved power supply parameters and performance, da kuma enhanced power supply safety. Ana yi amfani da shi da yawa a cikin power distribution stations da box-type substations a load centers like urban residential areas, high-rise buildings, large public buildings, da kuma industrial enterprises.

[0003] A shekarun da ya gama, enclosed ring main units suna da amfani da su da yawa a cikin substations, switching stations, da kuma user distribution cabinets. Duk da cewa most of these ring main units suna da amfani da su a ground floor ko basements, inda ventilation conditions suna da ma'ana masu da take rage, da kuma environmental humidity varies significantly. Wannan zai iya ba da kyauka tsakiyar zafi a cikin tana da kyauka tsakiyar zafi na ring main units. Long-term operation under such conditions can gradually reduce the insulation of the equipment within the ring main unit, leading to incidents such as equipment insulation breakdown and equipment explosion, seriously endangering the power grid and personal safety. Saboda haka, ita ce da ita buƙata da device wanda zai iya ba da kyauka tsakiyar zafi da tsakiya a cikin tana da kyauka tsakiyar zafi na ring main unit in coordination with existing control software.

Summary of the Invention [0004]

Muhimmiyar wannan hakuri shine da tana da kyauka tsakiyar zafi na ring main unit, don haka za a lura da technical problems existing in the prior art.

[0005] Don haka za a lura da objective na wannan hakuri, technical solution adopted by the present invention is as follows:

[0006] Tana da kyauka tsakiyar zafi na ring main unit, inda karamin ciki na tana da kyauka tsakiyar zafi na ring main unit yana da kungiyar karamin ciki, wanda ya shafi karamin ciki da karkashin koyarwa. Karamin ciki da karkashin koyarwa an samu da karkashin koyarwa, sentsa mai kyauka tsakiyar zafi, da kuma fan. Karamin ciki da karkashin koyarwa an samu da hawakin zafi/permeable holes. Fan an sa ta karamin ciki da karkashin koyarwa. Karkashin koyarwa suna da su daga baya zuwa baya a cikin karamin ciki. Karamin ciki na tana da kyauka tsakiyar zafi na ring main unit an samu da hawakawa, inda an samu pressure relief cover. Tatsuniya na pressure relief cover an samu da ventilation mechanism. Ventilation mechanism ya shafi louvers da filter screen da suke daga faduwar zuwa karamin ciki. Sentsa mai kyauka tsakiyar zafi, karkashin koyarwa, da kuma fan suna da suka kontrola a kan controller.

[0007] Furthermore, a fixed shaft an samu a hawakawa. Fixed shaft an haɗa da first end na pressure relief cover. Pressure relief cover an samu da ventilation holes. Second end na pressure relief cover an haɗa da piston rod. Cylinder an samu da switchgear cabinet shell a kan cylinder fixing bracket. Switchgear cabinet shell an samu da pressure sensor da audible alarm. Pressure sensor, audible alarm, da kuma cylinder suna da suka kontrola a kan controller.

[0008] Compared with the prior art, the beneficial effects of the present invention are: when the humidity is high and exceeds a preset threshold, the controller controls the heating rods to heat and the fan to blow air. The hot air is discharged upwards through the through-holes/permeable holes and expelled through the pressure relief cover, thereby achieving drying.

[0009]

An embodiment of the ring main unit according to the present invention.

Detailed Description [0012]

The following describes the present invention in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present invention and are not intended to limit the present invention.

[0013] It should be noted that the term "connected" and words used to express "connection," such as "connected to" and "linked," as used in this application, may mean that one component is directly connected to another component, or that one component is connected to another component through other components.

[0014] As shown in FIGS. 1 and 2, a ring main unit provided with an air circulation structure. The bottom of the ring main unit cabinet body is of a composite structure, comprising a heating layer. The heating layer is provided with heating rods, a humidity sensor, and a fan. The top wall of the heating layer is provided with through-holes/permeable holes. The fan is arranged on one side of the heating layer. The heating rods are uniformly arranged within the heating layer. The top of the ring main unit cabinet body is provided with an opening, where a pressure relief cover is installed. The middle part of the pressure relief cover is provided with a ventilation mechanism. The ventilation mechanism includes louvers and a filter screen arranged from top to bottom. The temperature sensor, heating rods, and fan are all connected to a controller.

[0015] It should be noted that the controller can be a single-chip microcomputer (microcontroller).

[0016] Furthermore, a fixed shaft is welded at the opening. The fixed shaft is hingedly connected to a first end of the pressure relief cover. The pressure relief cover is provided with ventilation holes. A second end of the pressure relief cover is hingedly connected to a piston rod. A cylinder is fixedly connected to the switchgear cabinet shell via a cylinder fixing bracket. The switchgear cabinet shell is also provided with a pressure sensor and an audible alarm. The pressure sensor, audible alarm, and cylinder are all connected to the controller.

[0017] Compared with the prior art, the beneficial effects of the present invention are: when the humidity is high and exceeds a preset threshold, the controller controls the heating rods to heat and the fan to blow air. The hot air is discharged upwards through the through-holes/permeable holes and expelled through the pressure relief cover, thereby achieving drying.

[0018] The above descriptions are merely preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered as falling within the protection scope of the present invention.
