Description
Technical field
The utility model relates to the bypass of high-pressure frequency-conversion drive system high-pressure frequency-conversion and switches cabinet.
Background technology
Along with the high speed development and the maturation of thyristor performance, high voltage frequency conversion equipment is used widely, and its use spreads all over industries such as generating metallurgy, petrochemical industry, mine.Its system's formation is mainly electric power incoming line switch cubicle, rectifier transformer, frequency converter cabinet, bypass switching group (being become by vacuum contactor cabinet or vacuum circuit-breaker group), filter reactor, variable frequency control cabinet formation, and Inverter Application makes that motor is stable, reliable, can adjust running status automatically by technological requirement.But because cabinet is switched in bypass is to be become by vacuum contactor cabinet or vacuum circuit-breaker group, causes that this bypath system investment is huge, floor space is big, and control is complicated, loaded down with trivial details, and the programed interlocking of electric means is unreliable.
Summary of the invention
The purpose of this utility model provides a kind of high-pressure frequency-conversion bypass and switches cabinet, and this device adopts three isolating switches to switch, and makes that load still can work on during the frequency conversion trouble hunting, thereby guarantees not delay production.
The cabinet content Description is switched in the bypass of the utility model high-pressure frequency-conversion:
Cabinet is switched in the high-pressure frequency-conversion bypass, it is characterized in that: the cabinet door of device is provided with auxiliary switch, and auxiliary switch is connected with operating grip by little connecting lever, is provided with three isolating switches in the cabinet, on each isolating switch, be provided with a connecting lever, connecting lever attended operation handle; Each isolating switch is provided with a matching used auxiliary switch, and auxiliary switch rotation support arm is connected with little connecting lever and cooperates drive disk assembly as auxiliary switch and isolating switch; On auxiliary switch, be provided with operating mechanism, operating mechanism one side installation procedure lock, opposite side is installed electromagnetic lock; The door procedure lock is installed on the Qianmen of cabinet; The branch that shows isolating switch is installed on the cabinet door, is closed the signal lamp of state.
It is to be main element with Eco-power high voltage isolator that cabinet is switched in the bypass of the utility model high-pressure frequency-conversion, and cabinet adopts standard sections, can be with each producer's frequency conversion tank combination.Main element is an isolating switch in the cabinet, makes electric loop possess obvious fracture when having a power failure, and is convenient to the security maintenance maintenance.This cabinet principal character is that electromagnetic lock and Mechanically programm lock is used in combination, accomplish isolating switch be subjected to program mandatory be defined in have a power failure operation and in accordance with regulations operating sequence operate.The cabinet door is the setting program lock also, makes within its open and close restricted program, guarantees to have a power failure to open the door.This cabinet can carry out communication with frequency conversion and connect with the supporting use of all kinds high voltage converter both at home and abroad, and switch and cabinet door status signal are provided.
This switching cabinet possesses the anti-misoperation function, simple to operate, be convenient to safeguard, investment is little, advantages such as floor space reduction, easy and simple to handle, safe and reliable, be superior to the by-pass switch group that the vacuum circuit-breaker cabinet becomes with the vacuum contactor group.This switch cubicle has also that volume is light, the inner space is rationally distributed, makes things convenient for advantages such as installation, strictly carries out high pressure " five is anti-" operation.

Embodiment
See Fig. 2, the high-pressure frequency-conversion bypass is switched cabinet cabinet 13 and is adopted section bar to make framework, and cold-reduced sheet is made dividing plate and shrouding, metallic element surface spray treatment.The cabinet door that cabinet is switched in the high-pressure frequency-conversion bypass is provided with auxiliary switch 2, and auxiliary switch is connected with operating grip 16 by little connecting lever 4, is provided with three isolating switches 14 in cabinet, and each isolating switch is provided with a connecting lever 15, and connecting lever 15 is connected with handle 16.
See Fig. 1, each isolating switch 14 is provided with the 2 supporting uses of an auxiliary switch, and auxiliary switch rotation support arm 3 is connected with little connecting lever 4 and cooperates drive disk assembly as auxiliary switch and isolating switch; On auxiliary switch 2, be provided with operating mechanism 6, operating mechanism one side installation procedure lock 5, opposite side is installed electromagnetic lock 7; Door procedure lock 8 is installed on the Qianmen of cabinet 13.The branch that signal lamp 1 shows isolating switch is installed on the plate door, is closed state.On the Qianmen, also be provided with form 9 and nameplate 10, on the Qianmen, also be provided with threshold switch 11 and door lock 12.
See Fig. 3, it is as follows that the cabinet operation sequence is switched in the high-pressure frequency-conversion bypass:
Sub-switching operation:
1. when isolating switch K2 divides state, divide to keep apart and close K1, divide then to keep apart and close K3, open the door;
2. when isolating switch K1 and K3 divide state, divide to keep apart and close K2, open the door.
Closing operation:
1. at first close the door, when isolating switch K2 divides state, close isolating switch K3, close isolating switch K1 then;
2. at first close the door, during at minute state, isolating switch K2 closes at isolating switch K1 and K3.Specific requirement is switched in frequency conversion:
Possess following locking: bypass isolating switch K2 and inlet wire isolating switch K1 and outlet isolating switch K3 mechanical interlocking between inlet wire isolating switch and outlet isolating switch and the lead-in circuit breaker (not at this cabinet), when being bypass isolating switch K2 closure, inlet wire isolating switch K1 and outlet isolating switch K3 can not close; When inlet wire isolating switch K1 and outlet isolating switch K3 were closed, bypass isolating switch K2 can not close; Lead-in circuit breaker DL when make position, electromagnetic lock 7 locking isolating switch 14 on all isolator operating mechanisms 6, all isolating switches 14 all can not be operated, and realize to switch the interlocking of cabinet with the lead-in circuit breaker cabinet.
