Longitudinal rotary cabinet is mainly composed of fixed cabinet body and extractable parts. According to the function of electrical equipment in the cabinet, the cabinet body is divided into four different functional units with metal partition: bus room, circuit breaker room, cable room and instrument room, and each functional compartment is provided with pressure relief channel. At the same time, a small bus room on the top of the cabinet is added for convenience of construction. The cabinet shell and the partitions of each functional unit are made of aluminum-zinc plate or cold-rolled steel plate and bolted after bending.
Longitudinal rotary intermediate cabinet can be partially equipped with longitudinal rotary isolation-circuit breaker, and can also be equipped with longitudinal rotary isolation-load switch, longitudinal rotary isolation handcart and longitudinal rotary isolation-fuse handcart according to the needs of the scheme, which is convenient for flexible combination of various primary system schemes. The installation and debugging of the vertical rotation center cabinet can be carried out at the same time in front of and behind the cabinet. If the circuit breaker needs to be overhauled and replaced, only the vertical rotation isolation-circuit breaker handcart needs to be pulled out, and the switch replacement can be completed in a short time, thus saving time and maintenance cost. Compared with similar products, this product has the characteristics of complex functions, small size, light weight, convenient maintenance, safety and environmental protection.

Functional composite, convenient operation and maintenance
The main switch ZXYV-12KV longitudinal rotation isolation-vacuum circuit breaker. It is a functional composite circuit breaker integrating vacuum circuit breaker, isolating switch, mechanism and interlocking. It organically combines the three functions of breaking, isolation and interlocking. The vacuum arc extinguishing chamber and isolation plug of the longitudinal rotation isolation-circuit breaker are respectively installed in the inner and upper and lower ends of the epoxy resin insulation cylinder. The epoxy resin cylinder is not only the insulation medium of the conductive circuit, but also the support of the switch component. And because of the longitudinal arrangement and integrated design, the longitudinal rotation isolation-circuit breaker is different from the traditional removal type circuit breaker, which adopts the central push-in and pull-out mechanism (no need to shake in and out of the chassis car).
At the same time, circuit breakers, isolating switches and interlocking devices between cabinet doors are also set up inside the operating mechanism to meet the "five prevention" requirements. After the vertical rotation isolation-circuit breaker is pushed into position, the positioning pin on the mechanism can be inserted into the front and rear positioning holes of the cabinet body. At this time, the mechanism does not move the pole to rotate 90 degrees counterclockwise. During the rotation of the pole, the interlocking device at the rear end synchronously opens the valve of the contact box. When the pole rotates to the vertical position (90 ", the isolation contact at the upper end of the pole is directly plugged with the busbar, the isolating contact at the lower end of the pole and the lower static contact seat are directly inserted to complete the closing operation of the isolating switch, and the circuit breaker can be closed at this time. On the other hand, when the circuit breaker is switched off, when the pole rotates clockwise to the horizontal position, the rear interlocking device will synchronously close the valve of the contact box. When the pole rotates to the horizontal position, the isolating switch will be switched off, and the locating pin will be released. At this time, the locating pin will be pulled out, and the longitudinal rotation isolation-circuit breaker can be pulled out of the cabinet as a whole.
Air insulation, safety and environmental protection
The main switch adopts vacuum arc extinguishing chamber, which meets the requirements of environmental protection and avoids the problems of maintenance, gas recovery and safety and environmental protection caused by the use of SF6 arc extinguishing. At the same time, the unique structure design (rotating circuit breaker pole to realize the function of isolating switch) is adopted to save the upper and lower isolating switches, thus realizing the purpose of using air insulation miniaturization. It subverts the traditional method of using insulation coating or using a large number of organic insulating material partitions in the cabinet in order to achieve miniaturization.Simple circuit, less heat source
The main circuit is connected by the main busbar arranged in the longitudinal horizontal direction with the upper end contact of the pole post of the longitudinal rotation isolation-breaker, the lower end contact of the pole post of the longitudinal rotation isolation-breaker is connected with the lower static contact, and the lower static contact is installed on the current transformer. The entire loop is vertically interconnected from top to bottom, and there is no transition branch bus and insulating support between the components. The conductive path is short, which effectively reduces the source of temperature rise.Obvious double isolation fracture
Isolation-the rotation of the circuit breaker can be operated manually or electrically. The operator can directly observe the whole process of the insertion and separation of the isolation moving and static contacts through the observation window, and can grasp the isolation state of the circuit breaker in real time. The user can also configure the display device on the instrument door as required, and can observe the plug-in state in the contact box through the display device, and can also directly observe the opening and closing state of the grounding switch from the observation window of the lower door.miniaturization
