Abstract
The utility model discloses a metal armored centrally-mounted withdrawable switch cabinet which comprises a switch cabinet body and metal septa, wherein the switch cabinet body is assembled by bolting and divided into a circuit breaker chamber, a bus chamber, a cable chamber and a relay instrument chamber by the metal separation plates, an isolation valve is arranged between the circuit breaker chamber and the bus chamber, a circuit breaker is arranged in the circuit breaker chamber, the circuit breaker is an indoor high-voltage vacuum circuit breaker, a main bus, a branch bus and a static contact box are arranged in the bus chamber, the main bus is fixed through the branch bus and the static contact box, a current transformer, a grounding switch and a plurality of cables are arranged in the cable chamber, and the rear part of the switch cabinet body is provided with a rear cover plate. The metal armored centrally-mounted withdrawable switch cabinet is small in size, low in energy consumption, moderate in price, and safe and reliable in operation. The indoor high-voltage vacuum circuit breaker in the switch cabinet has a modular spring operation structure which is convenient to replace, can be independently assembled and disassembled, but also guarantees the reliability of electrical connection.
Description
Technical field
The utility model belongs to indoor metal switch cabinet technical field, relates to the mid-withdraw-type switch cabinet of a kind of metal armouring specifically.
Background technology
Switch cubicle of the prior art mainly is indoor complete power distribution equipment; Accept and distribute the usefulness of electric energy as power plant, transformer station and industrial and mining enterprises; Be used for acceptance and distribution network electric energy and circuit is carried out control protection and monitoring, also can be used for the place of frequent operation.But switch cubicle of the prior art has that volume is big, and energy consumption is big, costs an arm and a leg; Easyly leak electricity, bus heating, insulating part be prone to shortcomings such as breakdown, so how can provide a kind of volume little, energy consumption is low; Moderate cost, the reliable switch cubicle of handling safety becomes the urgent demand of people.
The utility model content
The utility model provides a kind of volume little in order to overcome the deficiency that prior art exists, and energy consumption is low, moderate cost, the mid-withdraw-type switch cabinet of the reliable metal armouring of handling safety.
The utility model is realized through following technical scheme: the mid-withdraw-type switch cabinet of a kind of metal armouring; Comprise cabinet and metal partion (metp); Cabinet is assembled by bolted-on; Cabinet is divided into breaker chamber, bus-bar room, cable vault and relay control room by metal partion (metp), between breaker chamber and bus-bar room, is provided with Isolation Valve; The front portion of relay control room is provided with control room's door; Circuit breaker is installed in the breaker chamber, and circuit breaker is an indoor high-voltage vacuum circuit breaker, and the front portion of breaker chamber is provided with the breaker chamber door; Be provided with main bus bar, branch bar and fixed contact box in the bus-bar room; Main bus bar is fixed through branch bar and fixed contact box, and current transformer, earthed switch and some cables are installed in the cable vault, is provided with back shroud at the rear portion of cabinet.
Indoor high-voltage vacuum circuit breaker has modular spring actuating structure.
Cabinet and metal partion (metp) all are to be formed by cold-rolled steel sheet bolt after Digit Control Machine Tool processing and bending.
The beneficial effect of the utility model is: the mid-withdraw-type switch cabinet volume of the metal armouring of the utility model is little, and energy consumption is low, moderate cost, and handling safety is reliable.Indoor high-voltage vacuum circuit breaker in the utility model switch cubicle has modular spring actuating structure and modular secondary control unit; Not only be convenient for changing; Can independently load and unload, more guarantee the reliability be electrically connected, independently to be different from the framework that traditional mechanism must rely on circuit breaker be main body to modular mechanism; Change its defective that influenced by the behavior tolerance variation of framework, improved the reliability of circuit breaker greatly.When the equal reliable ground of all hardwares of the utility model, circuit breaker moved between test position and service position, Isolation Valve opened or closed automatically, has ensured that the staff does not touch electrified body.
