Technical field
The invention belongs to high voltage electric equipment technical field, be specifically related to a kind of switching mechanism for highly intelligent dual-power automatic switching device.
Background technology
In electric power networks, many users are had to require significantly high to power supply reliability, such as colliery and oil plant, once there is power outage in these units, great economic loss will be brought even to cause casualties to unit, so in the electric power system of these units, it is required for having main power source and stand-by power supply, when there is power outage in main power source, stand-by power supply must put into immediately and restore electricity, in order to realize this purpose, it is necessary to automatically switched between main power source and stand-by power supply by dual power supply switching mechanism.
Traditional dual power supply switching mechanism is to adopt two high-tension switch cabinets to add a set of extremely complex electric interlocking installation, is strictly on guard against two loop paired runnings.This Dual-power device has following three big defects: (1) locking is unreliable: at present, electrical interlocks reliability is too low, forbids to use, and mechanical interlocking device country, can only by various places designed, designed, transformation again without Uniting codes and standards.(2) complicated operation, and easy jam, cause electric power accident；(3) investment is big, need to purchase two switch cubicles, then design blocking device, then be retrofitted on switch cubicle.
Additionally, domestic dual power supply switching mechanism is usually two primary cut-outs of employing, the end of incoming cables Ge Jie mono-road power supply of every primary cut-out, then the leading-out terminal of two primary cut-outs is connected together, and realize main power source and stand-by power supply are switched rapidly by electric interlocking installation.The shortcoming of this dual power supply switching mechanism is that functional reliability is poor, and may result in major accident；It is such as when the power failure of main power source power supply circuits carries out regular maintenance, coil burnout in the primary cut-out of main power source connection may be fallen, but the circuit in this primary cut-out still keeps channel status, now, another primary cut-out in this kind of dual power supply switching mechanism can connect stand-by power supply at once and continue power supply, so by cause originally should the main power source power supply circuits of power-off also charged, it is easy to cause the maintainer generation electric shock accidents of maintenance main power circuit.Additionally, due to two primary cut-outs need to be purchased, invest also relatively larger.
Additionally, patent documentation CN101430986A discloses a kind of outdoor high-voltage permanent magnet type vacuum circuit breaker, including base, three poles being arranged on base and the permanent magnet type operating mechanism being arranged in base；This kind of vacuum circuit breaker can be effective to the break-make of single supply, but this kind of vacuum circuit breaker of separate unit can not realize dual power supply switching.
