Description

Technical Field

[0001] The utility model relates to the field of switch cabinets, in particular to an electric control door plate of a double-layer door of a switch cabinet. Background Art

[0002] KYN27 armored removable AC metal-enclosed switchgear (KYN cabinet for short) plays an important role in the power system and is widely used in substations. Like other products, KYN cabinets are constantly improving their functions in practice to meet user requirements. In recent years, from the perspective of operator safety and improving operating efficiency, users have increasingly demanded the use of electric-operated circuit breaker trolleys to push and withdraw from KYN cabinets, prompting manufacturers to further improve the functions of KYN cabinets and configure electric chassis vehicles in newly designed KYN cabinets to meet user requirements. However, there are still a large number of old equipment in operation, which require special personnel to use special operating handles to swing the circuit breaker trolley into the working position or out to the test position. In order to reduce manpower and improve protective measures, a large number of equipment in operation need to be modified.

[0003] However, the original cabinet itself cannot be operated electrically. If the solution of directly converting the manual chassis vehicle into an electric chassis vehicle is adopted, the interior of the cabinet needs to be modified. Since there are many KYN cabinet manufacturers, the chassis vehicles and cabinet structures used are diverse, the modification is difficult, and there is also the problem of affecting the cabinet quality assurance after the cabinet modification.

[0004] Therefore, other manufacturers currently install the electric operating mechanism on the outside of the KYN circuit breaker door panel, such as a switch cabinet with an electric operating device disclosed on June 16, 2020 and with a publication number of CN111293622A, comprising a cabinet body and a transport vehicle for carrying electrical equipment, the cabinet body being provided with a cabinet door, the transport vehicle comprising a vehicle body, an end beam and a screw rod, the end beam being provided on the cabinet body, one end of the screw rod being provided on the vehicle body, and the other end passing through the vehicle body and being provided on the end beam, and also comprising an electric operating device, the electric operating device being connected to the screw rod and driving the screw rod to make the vehicle body slide relative to the end beam, the electric operating device being provided on the cabinet door and being detachably connected to the cabinet door. This modification can achieve electric operation by driving a manual chassis vehicle through an electric operating mechanism. However, since the electric operating mechanism is exposed, this method has the following problems: the motor installed outside the door cannot conveniently connect the power cord to the cabinet; the motor operating hole is exposed to the outside, and the circuit breaker can be shaken into the insertion position of the switch cabinet by plugging in the operating handle, which cannot guarantee the safety of maintenance personnel and there are risks and operational hazards of simultaneous electric and manual operations; it is not beautiful and the motor protrudes too much and is easily bumped. Utility Model Content

At the same time, the electric operating mechanism in the motor box and the various components in the control box will not be exposed to the outside. After the transformation, remote operation can be realized in the control room, which increases the safety of the operator. During daily maintenance, the electric operating mechanism, control components and wiring terminals can be repaired and replaced by opening the corresponding switch door, which effectively ensures safety and simple control.

[0009] The electric operating mechanism can adopt the same structure as the electric operating device in CN111293622A; the types and quantities of the control components and wiring terminals in the control box can be configured accordingly according to the types of different switch cabinets.

[0010] In a preferred embodiment, a groove is provided on the rear side of the door panel body.

[0011] In a further preferred embodiment, the door panel body includes a front wall panel and two inclined wall panels, the two inclined wall panels extend backward from the two side edges of the front wall panel respectively, and the groove is formed between the front wall panel and the two inclined wall panels. After the door panel is replaced, the protruding parts of the original components in the switch cabinet can be placed in the groove and will not directly contact the door panel body, thereby avoiding damage to the components and affecting the line connection.

[0012] In a preferred embodiment, the switch door of the control box is provided with a plurality of switches and display windows. When controlling the switch cabinet, the switches on the switch door of the control box can be directly operated; and the display window can display various parameters in the cabinet.
