Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a non-assisted ventilation device for anti-condensation of the ring network cabinet. The hot air in the cable trench can only flow out of the cable trench from the sealing ring, causing the hot air in the cable trench to enter the cabinet, so as to realize timely ventilation inside the cable trench, reduce the temperature in the cable trench, and avoid air pollution in the cable trench. Hot air enters the cabinet to form condensation, thereby avoiding the corrosion of automatic mechanisms such as circuit breakers and load switches in the cabinet, which will cause the problem that the switch cannot operate correctly, improve the reliability of power supply, and do not need to spend a lot of manpower and material resources to complete the ring network. The erasure of cabinet condensation reduces potential safety hazards

Embodiment 1

[0035] An anti-condensation non-assisted ventilation device for a ring network cabinet, such as figure 1 with figure 2 As shown, it includes a support base 11 located above the cable trench and a cabinet body 10 located above the support base 11. The cabinet body 10 and the support base 11 are connected by bolts. The support base 11 is a shell structure with an open lower end surface, supporting The upper end surface of the seat 11 is provided with four ventilation devices, and the four ventilation devices are respectively arranged at the corners of the cabinet body 10. The upper end surface of the support seat 11 is provided with four through holes and a threading hole 12, and the threading hole 12 is connected with the cabinet body. cable fit in the body 10;

[0036] Such as Figure 3-6As shown, the ventilation device includes a wind cap 1, a connecting pipe 2 and a support tube 8; specifically: the wind cap 1 adopts a non-powered wind cap; The upper end surface of 8 and...

Embodiment 2

[0040] This embodiment 2 is the same as embodiment 1, the difference is that, as Figure 3-6 As shown, the present embodiment 2 is provided with an extension tube 17 in the connecting tube 2, specifically: the extension tube 17 is a transparent tube, the axis of the extension tube 17 coincides with the axis of the connecting tube 2, and the extension tube 17 and the connecting tube 2 Thread fit, the upper end of the extension pipe 17 is welded and fixed with the hood 1. By twisting the extension tube 17, the extension tube 17 is unscrewed out of the connecting tube 2, so that the total length of the connecting tube 2 and the extension tube 17 is increased, thereby extending the flow path of the air.

[0041] Further, the lower end of the connecting pipe 2 is provided with a diversion pipe 7, the inner cavity of the diversion pipe 7 is a gradually expanding structure from top to bottom, and the upper end of the diversion pipe 7 is connected with the connecting pipe 2, specifica...

Abstract

The invention discloses an anti-condensation unassisted ventilation device for a ring main unit, and relates to the technical field of ring main unit ventilation devices. The device comprises a support seat disposed above a cable trench and a cabinet body disposed above the support seat, wherein the cabinet body is connected with the support seat, and the upper end face of the support seat is provided with a plurality of ventilation devices. Each ventilation device comprises a wind cap, a connecting pipe and a support cylinder. The upper end of each connecting pipe is connected with the wind cap, and each support cylinder sleeves the corresponding connecting pipe. Each support cylinder is connected with the corresponding connecting pipe, and cooperates with a through hole in the upper endface of the support seat. A limiting plate is disposed between the connecting pipes and the support cylinders, and an elastic part is disposed between the limiting plate and the connecting pipes. Thewall of each support cylinder is provided with an installation hole, and the installation holes cooperate with the limiting plates. According to the invention, the hot air in the cable trench can be prevented from entering the cabinet body to generate a condensation phenomenon, and the device prevents the rusting of a switch in the cabinet body from causing the wrong operations, thereby improvingthe power supply reliability. Moreover, there is no need of a large amount of manpower and material resources for removing the condensation of the ring main unit, and the potential safety hazards arereduced.

Description

technical field [0001] The invention relates to the technical field of ventilation devices for ring network cabinets, in particular to a non-assisted ventilation device for anti-condensation of ring network cabinets. Background technique [0002] The ring network cabinet, that is, the ring network power supply unit RMU, is an emerging and rapidly developing smart grid power distribution equipment in recent years; the ring network cabinet includes a support seat above the cable trench and a cabinet above the support seat , the cabinet body is connected with the support base, the cable is coiled in the cable trench, and enters the ring network cabinet through the support base. [0003] When used in winter, the temperature difference between day and night is large. Since the cable trench is in a sealed space, the air in the cable trench is higher than the air in the ring network cabinet and the outside air. The hot air in the cable trench cannot circulate. It can enter the cab...
