Electrical control cabinet with heat dissipation protective device at top part

Abstract

The invention discloses an electrical control cabinet provided with a heat dissipation protective device at the top part. The electrical control cabinet comprises a control cabinet body, wherein an opening is formed in the front surface of the control cabinet body, one side of the opening is provided with a cabinet door, the cabinet door is connected with the control cabinet body through a hinge, one side of the cabinet door is provided with a lock catch, fan blades are driven to rotate by power, the heat of the electrical control cabinet is dissipated through the rotation of the fan blade, so that the electrical control cabinet has better heat dissipation effect, the lower end of a ventilation pipe is provided with a heat dissipation frame, the heat of the electrical control cabinet is dissipated more quickly by means of the heat dissipation frame, and the control cabinet body is protected by a protective plate and a protective frame, so that the control cabinet body is more solid. The electrical control cabinet provided with the heat dissipation protective device at the top part is simple in structure, can dissipate the heat inside the electrical control cabinet quickly, and can prevent tiny debris particles and a lot of dust from falling into the cabinet from the top part, thereby protecting the electrical appliance elements inside the electrical control cabinet and prolonging the service life of the electrical appliance elements.

Description

technical field [0001] The invention relates to the technical field of electrical control cabinets, in particular to an electrical control cabinet with a heat dissipation protection device on the top. Background technique [0002] The electrical control cabinet is mainly used for electrical operation and control of the mechanical equipment on site. There are many cables and electrical components installed inside the electrical control cabinet. Especially in recent years, with the advancement of science and technology, high-end precision electrical components have been widely used. Such as precision circuit breakers, frequency converters, PLC modules, relays, thermal stages, transformers, industrial computers, etc., these electrical components tend to generate heat during live work, resulting in excessive heat in the cabinet, affecting the performance of electrical components, and even Cause damage to electrical components, cause the electrical control cabinet to fail to work...

[0002] The electrical control cabinet is mainly used for electrical operation and control of the mechanical equipment on site. There are many cables and electrical components installed inside the electrical control cabinet. Especially in recent years, with the advancement of science and technology, high-end precision electrical components have been widely used. Such as precision circuit breakers, frequency converters, PLC modules, relays, thermal stages, transformers, industrial computers, etc., these electrical components tend to generate heat during live work, resulting in excessive heat in the cabinet, affecting the performance of electrical components, and even Cause damage to electrical components, cause the electrical control cabinet to fail to work normally, and further affect the normal operation of on-site mechanical equipment. In order to dissipate heat, cooling holes are often opened on the top plate of the control cabinet or fans are installed for ventilation, but the environment at the work site is relatively Poor, the dust is relatively large, and often small debris particles and a large amount of dust fall into the cabinet from the top of the fan blades, resulting in large dust in the cabinet, affecting the performance of electrical components, causing damage to electrical components, and even causing The fan is not working properly
