The utility model is to adopt following technical scheme to realize: a kind of distribution network systems vacuum circuit breaker that installs electronic position display unit additional, comprise that one with the vacuum circuit breaker of machinery indication arm and inner breaking coil, the housing exterior of described vacuum circuit breaker is also provided with three indicator lights; Enclosure is provided with the auxiliary relay of a moving fault, a storage battery and a charge power supply; Described first indicator light one end is connected with the positive terminal of inner breaking coil by a closing position sensitive switch; The other end of the first indicator light is connected with the negative pole end of inner breaking coil; One end of the second indicator light is connected with the positive pole of storage battery by open position sensitive switch, and the other end of the second indicator light is connected with the negative pole of storage battery; One end of the 3rd indicator light is connected with one end of auxiliary relay fixed contact, and the other end of auxiliary relay fixed contact is connected with the positive pole of storage battery, and the 3rd other end of indicator light and the negative pole of storage battery are connected; The coil of the described auxiliary relay composition control loop that is connected with the both positive and negative polarity of inner breaking coil; The inner breaking coil composition charge circuit that is connected with storage battery by charge power supply; Described machinery indication arm matches and realizes the folding of the two with closing position sensitive switch and open position sensitive switch respectively.
Design principle of the present utility model: utilize deciliter diverse location of Switch main body divide-shut brake machinery indication arm, install closure and disconnection that sensitive switch is realized corresponding indicator light additional.
On ZW8-12 type vacuum circuit breaker on outdoor lamppost operating mechanism shell, three kinds of indicator lights are installed.The bright representation switch closing position of the first indicator light, the bright representation switch open position of the second indicator light, the 3rd indicator light when bright switch co-bit circuit without electricity.
Machinery indication arm turns to closing position, and touching closing position sensitive switch makes its conducting, and now the first indicator light is bright, and second, third indicator light does not all work; When machinery indication arm turns to open position, touching open position sensitive switch makes its conducting, and now the second indicator light is bright, and the first and the 3rd indicator light does not work; When machinery indication arm turns to centre position, inner breaking coil is not charged, and the auxiliary relay of moving fault is without electricity, and fixed contact is closed, and now first, second indicator light does not work, and the 3rd indicator light is bright.
Pilot lamp power is obtained: the alternating current 220V power supply of the inner breaking coil of combined floodgate pilot lamp loop power utilization switch own, and when first, second indicator light work, inner breaking coil can charge to storage battery; Sub-gate circuit and the 3rd indicator light provide power supply by storage battery.
When this product is used, can judge three kinds of situations according to indicator light, the one, the charged closing position of switch, the 2nd, switch dead electricity sub-gate position, the 3rd, circuit dead electricity switch is in co-bit.
In conjunction with the multi-point and wide-ranging characteristic of mountain area distribution network, circuit breaking phenomenon is very frequent, but trouble shoot is because landform reason is very difficult, by the utility model is installed, can reduce tour distance; Electronical display is installed on switch, is easy to judge line fault and the scope of repair.
The design of indicator light makes the operating state of circuit breaker very clear, is more conducive to, to the maintenance of circuit breaker and fault judgement, effectively guarantee operating personnel's safety; Whole apparatus structure is simple, takes full advantage of the design feature of existing pole-mounted circuit breaker, low cost product.
