Description
Technical field
A kind of withdrawn type switch cabinet arranged in metal armor.
Background technology
Switch cubicle is industrial enterprise and uses three phase mains to do often power supply dynamic Control and the management equipment of use of department of power.
Switch cubicle in the past, accepts and distribution network electric energy the function to circuit implementation control protection and monitoring although have.But, still do not there is remote control, remote measurement, remote signalling and remote regulating function, do not possess by the total line traffic control field network with 485 communication interfaces, and prevent misoperation circuit breaker, prevent on-load push-and-pull handcart, prevent chargedly closing earthed switch, prevent earthed switch in earthing position power transmission and the feature such as prevent from being strayed into yet.Can not meet social progress and day by day flourishing industrial enterprise and use the demand of department that three phase mains the does power three-phase power switch cabinet to multi-functional, high-quality, high safety performance.
Summary of the invention
The object of the invention is to form by fixing cabinet and can extracting handcart two large divisions out by switch cubicle, in cabinet, is furnished with the design of handcart chamber, bus-bar room, cable vault, relay control room, low-pressure chamber, make the present invention not only there is function and the feature of former switch cubicle, also there is remote control, remote measurement, remote signalling and remote regulating function, with by with total line traffic control field network of 485 communication interfaces, and prevent misoperation circuit breaker, prevent on-load push-and-pull handcart, prevent chargedly closing earthed switch, prevent earthed switch in earthing position power transmission and the feature such as prevent from being strayed into.
The present invention is made up of cabinet, handcart chamber, bus-bar room, cable vault, relay control room, low-pressure chamber, pressure relief device, earthing device, in switch cubicle, be provided with dividing plate, dividing plate will be divided into handcart chamber, bus-bar room, cable vault, relay control room, low-pressure chamber in switch cubicle, indoor circuit breaker cart, voltage mutual inducer trolley, the metering handcart of being provided with of handcart, the height of all kinds of handcarts is consistent with degree of depth specification, handcart can exchange each other, handcart is provided with test position and service position in cabinet, and each position is equipped with interlocking positioner; In bus-bar room, be provided with main bus bar and branch bar, main bus bar causes another switch cubicle and is connected with fixed contact box by branch bar from a switch cubicle, all bus insulating sleeve plastic packagings, and the little bus of flat branch is bolted fixed contact box and main bus bar; In breaker chamber, be provided with the dividing plate valve of specific guide rail, fixed contact, the dividing plate valve of fixed contact is arranged on the rear wall of handcart chamber; In cable vault, be provided with current transformer, earthed switch, lightning arrester and cable, and the detachable aluminium sheet cracking in its bottom preparation; In relay control room and on control room's door, be provided with the instrument of relay protection element, charged supervision indicating device and lay the wire casing that control circuit is used; Above handcart chamber, bus-bar room and cable vault, be respectively equipped with pressure relief device; Secondary line on switch cubicle is connected by manual secondary plug with the secondary line of handcart, and the moving contact of secondary plug is connected by a nylon bellows and handcart, and secondary fixed contact pedestal is contained in the upper right side of switch cabinet handcart compartment; In cable vault, set up separately and run through adjacent each cabinet the grounding copper bar with cabinet good contact.
Special requirement and the course of work of the each part of the present invention are as follows:
Bus-bar room part: in the time of user and requirement of engineering, the connecting bolt on bus bar can encapsulate with insulating case and end cap.In the time that bus passes through switch cubicle dividing plate, fix with bus casing.Occur if any accident, effectively restriction accident of this setting spreads to adjacent cabinet, and can ensure the mechanical strength of bus.
Breaker chamber part:
The specific guide rail of circuit breaker indoor location, slides and works interior for circuit breaker cart.Handcart can move between service position and test position, and the dividing plate valve of fixed contact is arranged on the rear wall of handcart chamber, and handcart moves to the process of service position from test position, and valve is opened automatically.When the mobile handcart of opposite direction, dividing plate valve is completely compound, thereby ensures that operating personnel do not touch electrified body.Handcart can be closed in situation and be operated at cabinet door.Operating personnel can see handcart residing position in cabinet by observation window, divide-shut brake instruction and energy storage situation.
Cable vault's part:
Current transformer, earthed switch, lightning arrester and cable are installed in cable vault, and bottom, cable vault disposes the detachable aluminium sheet cracking, in order to guarantee the convenience of site operation.
Relay control room part:
The various control lines that the device that configures in relay control room and on control room's door uses are all laid in wire casing, and cover with metal cover board.Left side wire casing in order to control, introduce, lead-out groove by little line.The little wire routing of switch cubicle self inside, on right side, leaves little bus and passes through hole with convenient construction on the top board of relay control room.
Pressure relief device part:
Above handcart chamber, bus-bar room and cable vault, be equipped with pressure relief device.In the time of circuit breaker or bus generation Internal faults arc, inside switch cabinet voltage raises, and the special seal circle being installed on door seals cabinet face, and the earth pressure release metallic plate of top arrangement will be opened automatically, release pressure and excretion gas, to guarantee operating personnel and switch cubicle safety.
The interlocking part of the secondary line of secondary plug and handcart:
Because the secondary line interlocking of secondary plug and handcart arranges, handcart only, in the time of test position, could be inserted people and remove secondary plug.Handcart is in the time of service position, and due to mechanism's interlocking effect, the locked state of secondary plug can not be removed.
Earthing device part:
The grounding copper bar of setting up separately in cable vault, for direct ground connection components and parts.Meanwhile, because whole cabinet splices mutually with aluminizing zine plate, grounding copper bar can make whole cabinet in good earth state, guarantees operation, operating personnel's safety.
The present invention is reasonable in design, diverse in function, easy to operate, use safety, before having in switch cubicle function and feature, also there is remote control, remote measurement, remote signalling and remote regulating function, with the total line traffic control field network passing through with 485 communication interfaces, and prevent misoperation circuit breaker, prevent on-load push-and-pull handcart, prevent chargedly closing earthed switch, prevent earthed switch in earthing position power transmission and the feature such as prevent from being strayed into have practical use value and positive social effect.
