Abstract

The utility model discloses a natural cooling device for a transformer cabin. The natural cooling device comprises a transformer cabin body, an air exhaust port is arranged at the upper end of a wall on one side of the transformer cabin body, an air inlet is arranged at the lower end of the wall on one side of the transformer cabin body, electric fireproof shutters are installed on the air inlet and the air exhaust port, and each electric fireproof shutter comprises an electric fireproof valve and a shutter body. The natural cooling device is suitable for installation and running of an oil immersed transformer in a work shop where the height is limited, can naturally ventilate to cool the transformer cabin and effectively guarantees normal running of a transformer.

Description

A kind of natural cooling device of transformer room

Technical field

The utility model belongs to the ventilation of transformer room technical field, relates in particular to a kind of natural cooling device of transformer room.

Background technology

At present, some workshop is owing to affected by external condition, and the height-limited system in oil-immersed type transformer chamber adopts standard mode to be installed into air outlet window and can't satisfy transformer heat radiation requirement, and the equipment that affects normally moves.Existing solution commonly used has two kinds: 1, adopt dry-type transformer to be arranged in the workshop, the shortcoming of this method is that the transformer equipment expense is high, uncontrollable equipment cost; 2, mechanical ventilation equipment is set to solve ventilating problem in the oil-immersed type transformer chamber, the shortcoming of this method is because the transformer room is the Class C fire hazard, workshop, transformer place fire hazard mostly is fourth penta class, and is different from transformer room's fire hazard classification; Therefore, the exhaust blower of ventilation of transformer room heat transmission must be explosion-proof fan, for not affecting workshop condition, the heat that produces in the time of also need establishing the metal airduct transformer is moved is discharged to outside the workshop, for preventing fire spread, airduct is established operating temperature at transformer room's partition wall place be 70 ℃ fire resisting damper, and to give, exhaust blower carries out interlocked control, this method is electric or the equipment of ventilation equipment is all more loaded down with trivial details, investment is large, the control of fire resisting damper control cabinet is sent, the start and stop of exhaust blower system owing to be provided with, and has increased failsafe link.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of transformer room nature cooling device, can realize natural draft to the transformer room, has effectively reduced the working temperature of transformer, guarantees the transformer safe and reliable operation.

For achieving the above object, the utility model is by the following technical solutions:

A kind of transformer room nature cooling device, it comprises the transformer room, the upper end of one side walls of transformer room offers exhaust outlet, the lower end offers air inlet, electronic fire shutter all is installed on air inlet and the exhaust outlet, and described electronic fire shutter comprises electric fire-damper and shutter.

Described transformer room nature cooling device, it is provided with on the side walls of transformer room's wall of air inlet and exhaust outlet and is provided with the high voltage bus support, and the high voltage bus support is between air inlet and exhaust outlet.

Described transformer room nature cooling device, its bottom that is provided with on the wall of air inlet is provided with the wind hole.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

This transformer room nature cooling device is applicable to installation, the operation of oil-immersed type transformer in workshop when restricted of workshop inner height, can realize that natural draft lowers the temperature to the transformer room, has effectively guaranteed the normal operation of transformer.

Description of drawings

Fig. 1 is planar structure schematic diagram of the present utility model;

Among the figure: the 1-transformer room; The 2-transformer; The electronic fire shutter of 3-; 4-high voltage bus support.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

In conjunction with Fig. 1, a kind of transformer room nature cooling device, it comprises transformer room 1 and the transformer 2 that is placed in the transformer room, the upper end of one side walls of transformer room 1 offers exhaust outlet, the lower end offers air inlet, electronic fire shutter 3 all is installed on air inlet and the exhaust outlet, electronic fire shutter 3 comprises electric fire-damper and shutter, described electric fire-damper is in normally open at ordinary times, and when the gas flow temperature in the transformer room reached 70 ℃, shutter is closed and closed to electric fire-damper, and, electric fire-damper also can be according to engine request, and the output valve shutdown signal is with other fire-fighting equipment interlocking; Also be provided with high voltage bus support 4 offering on the side walls of air inlet and exhaust outlet, high voltage bus support 4 is between air inlet and exhaust outlet.The bottom that is provided with the body of wall of air inlet is provided with the wind hole, can assist air intake, so that better cooling transformer.

The utility model does not need to arrange mechanical ventilation equipment in actual applications in the transformer room, only use loss and version according to transformer, suitably adjusts the area into and out of air regulator of offering on transformer room's interior walls, to satisfy the natural draft requirement.

Claims (3)

1. transformer room nature cooling device, comprise transformer room (1), it is characterized in that: the upper end of a side walls of transformer room offers exhaust outlet, the lower end offers air inlet, electronic fire shutter (2) all is installed on air inlet and the exhaust outlet, and described electronic fire shutter comprises electric fire-damper and shutter.
