Description

A Moisture-proof Switch Cabinet Convenient for Maintenance in Rainy Days

technical field

The utility model relates to an electrical device, in particular to a heat dissipation and dehumidification switch cabinet.

Background technique

The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. One of the biggest problems in its use is poor heat dissipation. Usually, an exhaust fan is used to exchange heat between the switch cabinet and the outside air. However, this will cause the outside humid air to enter the cabinet, causing the electrical components in the cabinet. The insulation between the cabinets is reduced, which affects the normal use of electrical components; in addition, when the outdoor switchgear encounters rainy maintenance, it is easy to enter the rainwater from the cabinet door, which affects the normal use of electrical components, which is very inconvenient.

As a further solution of the utility model: a moisture-proof net is provided at the heat dissipation louvers.

As a further solution of the utility model: the free end of the air intake pipe is provided with a rain shield.

As a further solution of the utility model: the ventilation hole is arranged obliquely downward.

As a further solution of the utility model: the upper end of the file frame is provided with a notch for easy retrieval.

Compared with the prior art, the beneficial effect of the utility model is: the setting of the induced draft fan and the heat dissipation louver makes the flowing air form in the cabinet, completes the rapid heat exchange and improves the heat dissipation performance; the installation plate can be detachably installed on the fixed board, which makes the maintenance of the induced draft fan more convenient; the air intake pipe is set, and multiple pull-out drying units are arranged at intervals on the air intake pipe, so a single pull-out drying unit can be replaced as appropriate according to the failure of the desiccant to avoid The overall replacement results in a waste of desiccant. At the same time, the use of the pull-out drying unit makes the replacement of the desiccant quick and convenient. Moreover, since the air inlet pipe is arranged outside the cabinet, the replacement of the desiccant does not need to open the cabinet, which improves the operation. The safety of the safety; the rain shield is set to avoid water entering the free end of the intake pipe when it rains; the file box is set to place the electrical diagram of the electrical equipment in the cabinet, which is convenient for maintenance workers to repair; the rain shield is set to prevent water from entering when it rains The rainproof plate can be pulled out by the handle, which can not only cover the maintenance workers at the door of the cabinet from the rain, prevent them from getting wet, but also prevent rainwater from entering the cabinet from the door during maintenance, reducing the probability of electrical accidents.

In summary, the new structure design is reasonable, easy to use, can complete rapid heat exchange, improve heat dissipation performance; reduce waste when using desiccant, make the desiccant quick and convenient, and also improve the safety of desiccant replacement When it rains and repairs, it can not only cover the maintenance workers from the rain, but also prevent rainwater from entering the cabinet from the cabinet door, improving safety performance.
