Abstract
The utility model relates to a novel high voltage electric machine starting cabinet, which comprises a cabinet body. The lower part of the cabinet body is provided with grounding conflux copper bar, a power supply is connected with two rotating type insolating switches by main bus rows, then connected with a vacuum circuit-breaker, a mutual-inductor, a vacuum contactor, a starting reactor, and a lightning arrestor in sequence, and lead out from the bottom of the cabinet by a lead cables. The main bus bar rows can through between the cabinets, and can extend to the right and the left flexibly. The utility model has the function of startup and protection, can conveniently realize the positive and negative startups of the electric machine, and the protection grade can reach more than IP2X and meet the requirements of ''five-prevention''. The utility model can be used for starting and controlling the high voltage electric machine with alternating-current 50Hz, alternating-current 3-12 KV, and power reaching to 1600KW.
Description
Technical field
The utility model relates to a kind of fixed ac metal closing switch gear, particularly relates to a kind of start-up control equipment of high-voltage motor.
Background technology
Along with the electrical apparatus industry continuous advancement in technology, high performance new element continues to bring out, and has replaced original oil-minimum breaker or old-fashioned split type circuit breaker as high-performance, incorporate vacuum circuit-breaker; New GN30 rotary separation switch progressively replaces original GN6, GN8, isolating switches such as GN19; New operating mechanism such as JSXGN and electrically operated institution progressively replace older machines such as CS6-1.Therefore, national departments concerned is also more and more higher to the protection and the fool proof requirement of switch cubicle.But existing high-voltage motor starts cabinet, its function singleness, and main primary element is all more old-fashioned, out-of-date, and cabinet mostly is open type or degree of protection is low, has " five is anti-" incomplete defective.
The utility model content
The utility model aim to provide a kind of have start and defencive function, general structure is reasonable, element function advanced person, the degree of protection height can reach the startup cabinet of the high-voltage motor that " five is anti-" require.
A kind of novel high-pressure electric motor starting cabinet comprises cabinet, and the ground connection copper bar is arranged at the cabinet bottom, and power supply is connected to rotary separation switch through main bus bar row, connect vacuum circuit-breaker, instrument transformer, vacuum contactor more successively, starting reactor, lightning arrester is drawn at the bottom of cabinet by the outlet cable.
Described rotary separation switch is two, is arranged in parallel in the circuit, and power supply is introduced respectively through main bus bar row, incites somebody to action wherein two-phase phase modulation during access.
Described main bus bar row can connect between cabinet.
Described rotary separation switch is the GN30 rotary separation switch.
The utility model long service life, starting reactor has limited the starting current of motor when starter motor, has improved the influence to system's electrical network greatly, and vacuum circuit-breaker can be protected overload and short circuit.
Select two rotary separation switch for use, can not only realize easily motor just, reverse start, and improved the degree of protection that starts cabinet, can reach IP2X and more than, can satisfy " five prevent " requirement fully.Main bus bar row can connect between cabinet, expansion about carrying out neatly.
The utility model is used to exchange 50Hz, exchanges 3～12KV, and power is to the usefulness of the start-up control of the high-tension motor of 1600KW.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is a circuit connection diagram of the present utility model
Among the figure: 1-main bus bar row, 2-rotary separation switch, 3-vacuum circuit-breaker, 4-cabinet, 5-instrument transformer, 6-vacuum contactor, 7-starting reactor, 8-lightning arrester, 9-outlet cable, 10-ground connection copper bar.
Embodiment
As shown in Figure 1, special ground connection copper bar 10 is arranged at the preceding bottom of cabinet 4, power supply is connected to main bus bar row 1 after introducing and starting cabinet, and main bus bar row 1 can connect between cabinet, and main bus bar row 1 connects rotary separation switch 2, the leading-out terminal of rotary separation switch 2 connects the upper end of vacuum circuit-breaker 3, the lower end of vacuum circuit-breaker 3 connects instrument transformer 5, connects vacuum contactor 6 more successively, starting reactor 7, lightning arrester 8 is drawn from bottom of cabinet bulk by outlet cable 9 then.
Described rotary separation switch 2 can be set to two, is set up in parallel in circuit, and power supply is guided to two rotary separation switch respectively through main bus bar row 1, in the end of incoming cables, and the two-phase in the ABC three-phase of one of them and another phase modulation; At leading-out terminal, the outlet of two rotary separation switch converges the back and connects vacuum circuit-breaker 3.Be the GN30 rotary separation switch in the present embodiment, its isolation fracture is not only directly perceived as seen, and its dynamic and static fracture is isolated fully.Two GN30 rotary separation switch are operated by the JSXGN operating mechanism, two rotary separation switch 2 can not be with closing but can be with dividing, and starting the cabinet gate when having only two rotary separation switch 2 all to be in separating brake could open in release, also just can take key operated back door, back door, can prevent operating personnel's mistakenly entering charged chamber effectively.
Be provided with a cover interlock between operating mechanism and the vacuum circuit-breaker 3, can prevent on-load deciliter isolating switch.
Circuit connecting relation of the present utility model as shown in Figure 2.
