 Structure outlined 

 Switchgear of this model is in accordance with the provisions in the GB3906-91 armored away design, manufacture. Level of protection of the shell for IP4X; level of protection for each compartment IP2X. Switchgear components (referred to as car) away from the cabinet and can be composed of two parts. 
 Cabinet 
 This type of switchgear cabinet assembly structure, the main component is aluminum-zinc steel plate, made by CNC machining. Multiple bending process and pull the rivet nuts, high strength bolts, the switchgear to ensure sufficient strength and rigidity at the same time, lighter, stronger to resist the ability of the harmful gas corrosion, and look more beautiful. The cabinet structure in accordance with the cabinet of the main functional elements separated for the car room, main busbar room, cable room (current transformer room) and the relay room (see Figure 2). In addition to the relay room, and the remaining compartment set accident exhaust channel leading to the top of the cupboard. 
 The bottom of the car room, a car track for the movement of the car in the cabinet. Compartment installed in the main circuit of the static contact contact box and the main bus compartment and cable compartment connected. When the car in the test location or exit outside the cabinet, the activities of the curtain plate static contact cover to form an effective isolation; activities curtain panels open automatically, when the car move from the test position to working position, to ensure the smooth connection of the main circuit. Activities under the curtain board independence movement, and can be locked. Therefore, if necessary, maintenance personnel can lock the live side of the curtain plate, overhaul the other side of the main loop static contact. 
 The main bus indoor installation of a three-phase rectangular copper bus. The main bus of the switchgear room by tube connected to the main busbar room cabinet in the run-time is separated to avoid an interval unexpected to hurt other switchgear scalability accident occurred. 
 Cable indoor according to the needs of the main loop program, you can install the current transformers, grounding switch, charged the display device and a fixed main cable architecture, accessories. The switch cabinet on the floor to open the main cable into the hole and removable closure plate. Each phase of the switchgear and connected to the root of l-3 single-core cable. 
 The relay room is used to install the protection, control, and the secondary component. The left side of the small room equipped for the control cable out of the trough: in a small room at the top has a small bus through the hole, the wiring when the top cover can be rotated to facilitate the installation of a small bus. Need to observe the instrument device can be installed on the door of relay room, regular operation of the switch and embedded relay. 


 Car 
 According to the different components of the main circuit configuration of a small car, car circuit breakers, voltage transformers car, isolating car and measurement car. All kinds of car building block changes in modulus with the specifications of the car to ensure interchangeable. Car location and the location of the test (disconnect) two targeted locations in the cabinet. The advancement of the car (exit) using a worm gear and effort institutions, lightweight, and flexible. Car out of the cabinet outside, you need to configure the dedicated transshipment trolley. 
 The car transporter car brought into cabinet, first locate the location of the test (disconnect), the car with the cabinet is locked, you can shake the advance mechanism will push the car to a working position. Car to reach the working position, shake shake blocked the car in place. Car interlocking institutions to ensure that only the circuit breaker in the state of the sub-gate, the car can not be moved, the only car in the positioning of the test (disconnect) position or work location, the circuit breaker before closing. 
 Interlock 
 ● This type of switchgear design a reliable "five anti-locking system. 
 A. Circuit breaker to prevent accidental cooperation, sub-operation, we recommended the adoption of the breaker control switch with red, green flop to achieve. Users accustomed to using other anti-misuse measures may be made when ordering. 
 B. The switch cabinet latch to ensure that the breaker car in the test or working position, the circuit breaker can be carried out together, sub-operation, the circuit breaker closing, the car will not be able to exercise. Prevent the loading pulling the car. 
 C. The switch cabinet latch guarantee only if the earthing switch in the OFF position, the car from the test position to move to the working position; only when the car in the test position, the earthing switch closing operation. In addition, the grounding switch is necessary, you can configure the live display device. Therefore, the charged closing earthing switch and earthing switch can prevent the misuse occurred in the transmission of the closing state. 
 D. The switch cabinet latch to ensure that the grounding switch is not closing, the next door and cabinet back door can not open the cabinet before. In order to prevent mistakenly charged interval. 
 ● Vice secondary plug and car position interlock. 
 The secondary of the switchgear cabinet and trolley lines connected through the second plug. 
 Secondary plug is connected by a corrugated extension tube and trolley; the second outlet installed in the top right of the cabinet trolley room. The only car in the test position, you can plug in or unplug the secondary plug. The car in working position, the interlock secondary plug is locked so that it can not be pulled. If the secondary power supply is not connected to the circuit breaker closing institutions can be electromagnetic locks.
