Description
Technical field
The utility model relates to a kind of outdoor high-voltage switch operating power self-energizing system, belongs to electric wiring power supply technique field.
Background technology
Outdoor high-voltage switch operates in the circuit of 10Kv-35Kv, because AC 220 V voltage on outdoor high-voltage circuit makes power supply for switch, all adopt at present and connect 1 voltage transformer on high-voltage line, voltage transformer secondary side exports 220 volts or various voltages lower than 220 volts, uses to outdoor high-voltage switch operation divide-shut brake.Because outdoor voltage transformer has tens jin of weights, make troubles to installation, high-voltage mutual inductor works for a long time out of doors in addition, and voltage transformer is not long for useful life, and dangerous, and the accidents such as time burns out, blast occur.
Utility model content
The utility model is for above-mentioned defect, and it is simple that object is to provide a kind of structure, very easy to use, safe outdoor high-voltage switch operating power self-energizing system.
The technical solution adopted in the utility model is for this reason: the utility model comprise be arranged on getting of Current Transformer Secondary side can coil, getting can coil and rectifier series connection, then in parallel with battery pack, battery pack overcharge protection circuit.
Described battery pack overcharge protection circuit: comprise a discharge circuit; described discharge circuit is provided with two input pins and an output pin; wherein an input pin input voltage is constant; another input pin input voltage is adjustable; described output pin outputs signal according to the voltage compare of two input pins; described output pin is connected with the base stage of a triode, the emitter and collector of described triode and discharge circuit two input pins are provided to the lines in parallel of input voltage.
Describedly for discharge circuit two input pin provides the circuit of voltage be:
There is provided the circuit of constant voltage: comprise the resistance and diode that are arranged in series, be provided with a bit between described resistance and diode, this is by being wired to an input pin of discharge circuit;
There is provided the circuit of adjustable voltage: the fixed resistance and the swept resistance that comprise series connection, the sliding point of described swept resistance is connected to another input pin of discharge circuit;
Described two lines in parallel are arranged.
The utility model has the advantages that: the utility model exports series connection one in Current Transformer Secondary and gets and can carry out getting energy by coil, eliminates an outdoor high-voltage mutual inductor, very easy to use, safety.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
The utility model comprise be arranged on getting of Current Transformer Secondary side can coil, getting can coil and rectifier series connection, then in parallel with battery pack, battery pack overcharge protection circuit.
Described battery pack overcharge protection circuit: comprise a discharge circuit; described discharge circuit is provided with two input pins and an output pin; wherein an input pin input voltage is constant; another input pin input voltage is adjustable; described output pin outputs signal according to the voltage compare of two input pins; described output pin is connected with the base stage of a triode, the emitter and collector of described triode and discharge circuit two input pins are provided to the lines in parallel of input voltage.
Describedly for discharge circuit two input pin provides the circuit of voltage be:
There is provided the circuit of constant voltage: comprise the resistance and diode that are arranged in series, be provided with a bit between described resistance and diode, this is by being wired to an input pin of discharge circuit;
There is provided the circuit of adjustable voltage: the fixed resistance and the swept resistance that comprise series connection, the sliding point of described swept resistance is connected to another input pin of discharge circuit;
Described two lines in parallel are arranged.
The utility model: 1) get and can get in Current Transformer Secondary side by coil, so just can do a standard and get energy coil, because no matter primary current is how many, and secondary output is unified 0-5A output, at present existing getting can instrument transformer, it be size according to primary current and design that secondary side gets can data;
2) excess voltage protection, current overvoltage protection is released by a high-power resistance, and resistor power is large, heating, failure rate is higher, and our design is can the short circuit of coil primary side by getting, get energy coil Non voltage output, protection battery pack overcharges and damages battery; Its principle: circuit R1 and D1 is connected on A point has a stable voltage to be supplied to discharge circuit reference voltage.R2 and P1 forms a sampling voltage, when voltage is higher than 27V, the current potential of P1 central point B is higher than reference voltage, discharge circuit 1 pin exports high electricity frequently, the conducting of Q1, E, C pole, relay J 1 action, three get can coil once by short circuit, get energy coil secondary Non voltage output, get energy circuit to batteries charging.
