Description
Technical field
This utility model belongs to high voltage electric equipment technical field, is specifically related to a kind of intelligent high-voltage dual power vacuum circuit breaker.
Background technology
In electric power networks, many users are had to require the highest 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, need to be 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 use 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 the lowest, forbids to use, and mechanical interlocking device country, can only be by various places designed, designed, transformation again without Uniting codes and standards.(2) operation complexity, and easily 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 and uses two primary cut-outs, 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 cause major accident；E.g. 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 the most should the main power source power supply circuits of power-off the most charged, it is easy to cause the maintainer generation electric shock accidents overhauling main power circuit.Additionally, due to two primary cut-outs need to be purchased, invest the biggest.
Additionally, patent documentation CN101430986A discloses a kind of outdoor high-voltage permanent magnet type vacuum circuit breaker, three poles including base, 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.
Utility model content
The purpose of this utility model is to provide a kind of intelligent high-voltage dual power vacuum circuit breaker being capable of Dual-power automatic switching.
The technical scheme realizing this utility model purpose is: a kind of intelligent high-voltage dual power vacuum circuit breaker, three poles including the base being provided with opening/closing operation mechanism, being arranged on base and dual power supply switching mechanism；Each pole is sequentially provided with along direction from top to bottom into electrical connection row, has static contact and the vacuum interrupter of moving contact and the insulation column being connected with moving contact；The middle part of each pole is additionally provided with the electrical connection that goes out electrically connected with a corresponding moving contact and arranges；Respectively enter the static contact electrical connection of electrical connection row and a corresponding vacuum interrupter；Opening/closing operation mechanism drives moving contact to do divide-shut brake action by each insulation column；Dual power supply switching mechanism include rotating be arranged on respectively to enter the isolation knife on electrical connection row, the isolating frame being fixedly installed on base, three the first power-line terminals being arranged on isolating frame, the second source binding post being fixedly installed on each pole and be arranged on isolating frame for the handover operation mechanism driving isolation knife to switch between the first power-line terminal and second source binding post.
This utility model is on the basis of traditional three pole type outdoor high-voltage vacuum breakers, add dual power supply switching mechanism, make its separate unit vacuum circuit breaker can realize the function of Dual-power automatic switching, owing to it is relatively reasonable in structure, take up room less, stable and reliable for performance, thus there is extremely wide application prospect.
