Problems solved by technology
[0002] In the existing electrical cabinets, in order to ensure the safe operation of the entire power system, corresponding relay protection devices need to be equipped. It may not be necessary to install a relay protection device, and if the location is reserved, it may affect the overall layout of the electrical cabinet; in addition, during the use of the relay protection device, it is necessary to ensure that the installation area has a good ventilation and heat dissipation effect, but for those without relay protection There are certain requirements for the ventilation holes of the electrical cabinet of the device. If there are too many, dust will enter the electrical cabinet and affect the service life of electrical components. With the development of the electrical system, the market demand for control cabinets that can adapt to different working scenarios is increasing. Therefore, it is very necessary to design and a control cabinet that can well meet the corresponding use requirements with or without relay protection

The invention discloses a relay protection control cabinet. According to the technical scheme, the device comprises a cabinet body, a cabinet door which is provided with a normally open air hole; adjustable air holes are formed in the side wall of the cabinet body; a supporting plate is hinged to the inner side wall of the cabinet body; a through hole is formed in the end surface of the supportingplate; when the supporting plate is in a vertical state, the axes of the through hole and the adjustable air hole are positioned on the same horizontal line; a movable baffle is arranged on the end face of the supporting plate, a first spring is connected between the movable baffle and the supporting plate, a connecting hole is formed in the end face of the supporting plate, when the first springis in the original length, the connecting hole is communicated with the through hole, and when the supporting plate is in the vertical state, the movable baffle slides downwards relative to the supporting plate to enable the connecting hole and the through hole to be staggered. The cabinet door is hinged to the cabinet body, when the cabinet door is opened, the supporting plate can rotate arounda hinge point, and when the cabinet door is closed, the supporting plate cannot rotate around the hinge point. According to the invention, the space in the cabinet body and the heat dissipation protection of the relay protection device can be effectively integrated, and the market demand is met.
