Description
Technical field
The present invention relates to a kind of high-voltage switch gear structure-design technique field, be specifically related to a kind of intelligent duplicate power supply conversion switch.
Background technology
In electric power networks, there are many users to require very high to power supply reliability, for example colliery and oil plant, in a single day power outage takes place in these units, will bring great economic loss even cause casualties to unit, so in the electric power system of these units, all need to have main power source and stand-by power supply, when power outage appears in main power source, stand-by power supply must drop into immediately and restore electricity, in order to achieve this end, need between main power source and stand-by power supply, carry out manual switchover or automatic switchover by the duplicate supply switching mechanism.
Traditional duplicate supply switching mechanism is to adopt two high-tension switch cabinets to add the extremely complicated electric interlocking installation of a cover, is strictly on guard against two loop paired runnings.This duplicate supply device has following three big defectives: (1) locking is unreliable: at present, the electrical interlocks reliability is too low, forbids to use, and mechanical interlocking device country does not have unified design specification standard again, can only be designed voluntarily, be transformed by various places.(2) complicated operation, and easy jam cause electric power accident; (3) investment is big, need purchase two switch cubicles, designs locking device then, is retrofitted on the switch cubicle again.
Domestic duplicate supply switching mechanism generally is to adopt two circuit breakers at present, the end of incoming cables of every circuit breaker is connect one road power supply, leading-out terminal with two circuit breakers connects together then, and realizes main power source and stand-by power supply are switched by electric interlocking installation.The shortcoming of this duplicate supply switching mechanism is that functional reliability is relatively poor, and may cause serious accident; For example be when regular maintenance is carried out in the power failure of main power source power supply circuits, coil burnout in the circuit breaker that main power source may be connected falls, but the circuit in this circuit breaker still keeps channel status, at this moment, another circuit breaker in this kind duplicate supply switching mechanism can connect stand-by power supply at once and continue power supply, the main power source power supply circuits that will cause script should cut off the power supply like this are also charged, are easy to cause the maintenance personal who overhauls main power circuit that electric shock accidents takes place.In addition, owing to need purchase two circuit breakers, invest also bigger.
Whole missions of circuit breaker, be the branch that is embodied in contact after all, close in the action, realize by operating mechanism and divide, close action, so the quality of the service behaviour of operating mechanism and quality, play a part very important the service behaviour and the reliability of circuit breaker.The operating mechanism of switchgear needs more machine components to form, and this is the cost height not only, and reliability is low, is directly proportional because the possibility that failure rate rises is a quantity with part.Operating mechanism at present commonly used has two kinds of spring mechanism and electromagnetic mechanisms.Spring operating mechanism is the spring that utilizes energy storage makes the circuit breaker action for power a operating mechanism.Spring energy-storage is normally finished by deceleration device by motor.Whole operating mechanism is broadly divided into spring energy-storage, keep and close a floodgate and combined floodgate is kept and four parts of separating brake.The advantage of spring operating mechanism is not need powerful DC power supply, and motor power (output) is little, AC/DC, suitable alternating current operation; Its shortcoming is the structure more complicated, number of spare parts many (being about 200), and require the machining accuracy height, and the manufacturing process complexity, the cost height, the reliability of mechanism is difficult for guaranteeing.The advantage of electromagnetic operating mechanism is simple in structure, number of spare parts few (being about 120), reliable operation, low cost of manufacture, but the power that its shortcoming is a closing coil to consume is too big, the pressure of contact is less, adds the heaviness of mechanism, and operate time, length required the user to be equipped with expensive batteries etc.
