StructureIntroduction
The switch equipment is designed according to GB3906-91 metal armoring seal switch equipment. The rectifier body is made up of the cabinet body and draw-out parts (namely handcart) placed in the middle. See charter 1. The cabinet divides into four separate rooms, the outer covering protection grade is IP4X,when each small room and the circuit breaker is opened, the protection grade is IP2X.It can suspend the inlet, outlet line, cable 's inlet, outlet line and other function plan. After arranged and combined, it can become each kind of plan form of the power distribution equipment. This switch equipment may be installed and maintained from the frontage, therefore it may compose the dual arrangement back to back and be installed against the wall, improving the switch equipment's security and flexibility and making full use ofthe occupying area.
SwitchgearstructurediagramSwitchgearDimensionsDescription of internal structureHandcart The framework of handeart is made of steel sheet through the procession ofCNC machine tool and rivet welding. According to the application, the handcarts can be divided into circuit breaker hand-cart, voltage transformer handcart, isolating handeart and metering handcart, etc. The handcarts of the same specifcation can be exchanged conveniently. In the cabinet, the handeart has isolating position, testing position and operating position, each of which is designed with a location device to assure that the handcart can't move easily at the above-mentioned positions, while the interlock must be unlocked to move the handcart.Bus chamberThebusbaris led fromone switchcabinet to anotherone andfixed with static contact box through branch bus. The flat branch bus is connected through the bolt to the static contact box and main bus,not needing any other line clamps or insulators. When there is special demand of the clients or the project, the connecting bolt on the bus bar can be encapsulated with insulation and end cap. When the bus crosses the bafle of the switch cabinet, fix it with bus bushing, so that, if there is any internal fault arc, it can prevent the fault spreading to another cabinet and can guarantee the me-chanical strength of the bus.Cable chamberInside the cable chamber, the current transformer, grounding switch, arester and cable can be italled, and on the bottom is designed sotted
removable aluminum sheet to assure the convenient site construction.Pressure releasing deviceRelay instrument chamberRelay instrument chamber is used to install all kinds of components, such as relays, instruments, signal indicator and operating switch, etc. In adition, it's available to add a small bus chamber on the top of the instrument chamber according to the demand of the clients, and set 16 lines to control the small bus.
Pressure releasing deviceOn the handcart chamber, bus chamber and cable chamber is intalleld pessre releasing device. When there is internal fault arc in the breaker, main bus or inside the cable chamber, and with the appearance of electric arc, the internal pressure in the switch cabinet rises. After irises to a certain pressure, the pressure releasing metal sheet of the top device will be opened automatically, and the pressure and the gas are released to guarantee the safety of the operator and the switch cabinet.Latching deviceLatching device is used to connect the central exit and cabinet body, and the lifting device is also designed to make it more convenient to open the central exit. When the central exit stays closed,the connecting strength with the cabinet body is the best and the capability against the internal arcing fault efctively is strengthened.
