In the high-low voltage detection circuit, when the power voltage input to the electric equipment is about 220V, the relay K cannot be electrified and sucked, and the subsequent electric telescopic rod M cannot enable the breaker body to be switched off; when the voltage is lower than 235V, the power supply voltage is lower than the trigger voltage (0.8V) of the controllable silicon VS after the transformation of the transformer T, the rectification of the rectifier bridge stack A2 and the voltage reduction and current limitation of the adjustable resistor RP, so that the controllable silicon VS cannot be conducted; in practical situations, when the voltage is higher than 235V, the power supply voltage is higher than the trigger voltage of the thyristor VS after transformation by the transformer T, rectification by the rectifier bridge stack a2, and voltage reduction and current limitation by the adjustable resistor RP, so that the thyristor VS is triggered and conducted (the positive electrode of the storage battery G enters the anode of the thyristor VS through the control power supply input end of the relay K2 and the normally closed contact end), and then the relay K is powered to pull in two control power supply input ends and two normally open contact ends of the relay K to be respectively closed, and two control power supply input ends and two normally closed contact ends of the relay K to be respectively opened. In the high-low voltage detection circuit, when the power supply voltage input to the electric equipment is higher than 198V, the power supply voltage is higher than the base electrode 0.7V initial voltage of an NPN triode Q1 after transformation by a transformer T, rectification by a rectifier bridge stack A2 and voltage reduction and current limitation by an adjustable resistor RP1, so that the NPN triode Q1 conducts a collector to output a low level to enter the positive power supply input end of a relay K1, and the relay K1 is electrified to attract the control power supply input end and a normally closed contact end to be open; because the normally closed contact end of the relay K1 is connected with the control electrode of the silicon controlled rectifier VS through the resistor R for voltage reduction and current limitation, the silicon controlled rectifier VS cannot be triggered and conducted at the moment; when the power supply input to the electric equipment is lower than 198V, the power supply voltage is lower than the initial voltage of 0.7V of the base electrode of the NPN triode Q1 after transformation by a transformer T, rectification by a rectifier bridge stack A2 and voltage reduction and current limitation by an adjustable resistor RP1, so that the NPN triode Q1 is cut off, the control power supply input end and the normally closed contact end of the relay K1 are not closed after power loss, the positive electrode of the power supply output by the storage battery G passes through the normally closed contact end of the relay K1 and is subjected to voltage reduction and current limitation by a resistor R, and the electrolytic capacitor C1 delays for 0.5 second to trigger the silicon controlled rectifier VS control electrode (the electrolytic capacitor C1 mainly plays a charging delay role, delays for about 0.5 second, prevents the silicon controlled rectifier VS from being triggered and conducted just before the normally closed contact end of the power supply input end of the relay K1 is disconnected in an initial state, and the power supply attraction time of the relay K1 is, then, the silicon controlled rectifier VS is triggered and conducted, and then the relay K is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay K to be respectively closed, and the two control power supply input ends and the two normally closed contact ends of the relay K to be respectively opened. Through the circuit effect, when the power supply voltage input to the electric equipment by the circuit breaker body is between 198V-235V, the relay K can not be electrically attracted, the follow-up circuit breaker body 1 can not be opened, and when the power supply voltage input to the electric equipment by the circuit breaker body is below 198V and above 235V, the relay K can be electrically attracted, so that preparation is made for the follow-up circuit breaker body 1 to be opened.

Fig. 1, 2, and 3 show, in the high-low voltage detection circuit, after relay K got electric actuation, because, two normally open contact ends of relay K and electric telescopic handle M positive and negative poles power input end connect respectively, so electric telescopic handle M can get electric work its plunger rod through lower connecting plate 71 at this moment, upper connecting plate 104 drives the operating handle axostylus axostyle 102 of circuit breaker body to descend, and then axostylus axostyle 102 drives the operating handle of circuit breaker body to descend, circuit breaker body 1 accomplishes the separating brake action (lower connecting plate 71, upper connecting plate 104 is in the descending, lower connecting plate 71, rotate along the pin joint between the upper connecting plate 104, upper connecting plate 104 upper end is along rotating with the pin joint between axostylus axostyle 102, guaranteed that circuit breaker body 1. Under the actual condition, the plunger rod of the electric telescopic rod M moves downwards for 2cm, and then can stop moving under the action of the internal limit switch, at the moment, the operating handle of the circuit breaker body 1 moves from the upper stop point to the position close to the lower stop point, and the opening action of the circuit breaker body 1 is completed. In the time delay circuit, when the field voltage is below 198V and above 235V, and the silicon controlled rectifier VS is conducted, the positive electrode of the power supply output by the silicon controlled rectifier VS cathode can also enter the other end of the resistor R, the high level is subjected to voltage reduction and current limitation by the resistor R to charge the electrolytic capacitor C3, within 2 minutes from the beginning, the electrolytic capacitor C3 is not fully charged, the high level of the 12V power supply is subjected to voltage reduction and current limitation by the resistor R, R3 to enter the NPN triode Q base voltage which is lower than 0.7V, the NPN triode Q is cut off, the relay K2 cannot be powered and attracted, and then the relay K continues to be powered and attracted; when the high level is subjected to voltage reduction and current limitation by the resistor R to charge the electrolytic capacitor C3, the electrolytic capacitor C3 is fully charged after the time exceeds 2 minutes, the high level of the 12V power supply is subjected to voltage reduction and current limitation by the resistor R, R3, the voltage of the base electrode of the Q transistor of the NPN triode is higher than 0.7V, the Q conduction collector of the NPN triode outputs the low level to enter the negative power supply input end of the relay K2, and then the relay K2 can be electrified to attract the control power supply input end and the normally closed contact end to be open; because the silicon controlled rectifier VS anode is communicated with the 12V power supply anode through the relay K2 normally closed contact end, the silicon controlled rectifier VS anode loses voltage at the moment, and then the relay K loses power and is not pulled in (at the moment, the 12V power supply does not charge the electrolytic capacitor C3 through the resistor R), after 2 seconds, when the voltage charged on the electrolytic capacitor C3 is not enough to maintain the conduction of the NPN triode Q, the relay K2 loses power again to control the power supply input end and the normally closed contact end to be closed again, and then the silicon controlled rectifier VS anode gets power again, so that preparation is made for controlling the opening of the circuit breaker body for the next voltage or high or low voltage. After the positive pole of the controlled silicon VS is electrified again, if the input power supply of the circuit breaker body returns to normal at the moment, the controlled silicon VS is not triggered any more, the relay K is in a power-off state, and the two control power supply input ends and the two normally-closed contact ends are closed respectively. Because, two normally closed contact ends of relay K and electric telescopic handle M negative and positive two poles power input end are connected respectively, so electric telescopic handle M can get electrician to do its plunger rod through lower connecting plate 71 at this moment, upper junction plate 104 drives the operating handle axostylus axostyle 102 of circuit breaker body and goes upward, and then axostylus axostyle 102 drives the operating handle of circuit breaker body and goes upward, circuit breaker body 1 accomplishes the action of closing a floodgate (lower connecting plate 71, upper junction plate 104 go upward in, lower connecting plate 71, rotate along the pin joint between upper junction plate 104, upper junction plate 104 upper end along with the pin joint between the axostylus axostyle 102 rotate, the. Under the actual condition, the plunger rod of the electric telescopic rod M moves up by about 2cm and then moves back and forth, and can stop moving under the action of the internal limit switch, so that the operating handle of the circuit breaker body 1 just moves from the lower dead point to the position close to the upper dead point, and the switching-on action of the circuit breaker body 1 is completed. Through above-mentioned circuit and mechanism combined action, this is novel temporarily too high or low circuit breaker body separating brake back at field voltage, and certain time interval meeting automatic control circuit breaker body closes a floodgate, has guaranteed to get electric work in the time as short as possible with the consumer. In actual conditions, the relay K2 is powered on, and within the first 2 seconds of power loss of the relay K, the electric telescopic rod M already drives the breaker body to be switched on (the electric telescopic rod needs about 5 seconds to complete switching on), so the switching-on speed is faster. In actual conditions, the circuit breaker body is switched on, if the field voltage is still too high or too low, the relay K can be electrified, and then the circuit breaker body is switched off again (the upward switching-on and the downward switching-off of the circuit breaker body both have certain allowance, namely the switching-on and switching-off functions are completed before the circuit breaker body approaches a bottom dead center or a top dead center for a certain distance) until the input power supply voltage is normal.

As shown in fig. 3, when the field voltage is high or low, the NPN transistor Q is turned on, and the relay K2 is powered on, and the low level output by the collector of the NPN transistor Q also enters the pin 3 of the short message module a1, so that the short message module a1 sends the short message stored inside through the wireless mobile network under the action of its internal circuit, and after receiving the short message, the mobile phone of the manager can visually know that the voltage is unstable on the field in the first time, and then receive the short message many times (once per minute brake, when the thyristor VS is turned on, the pin 3 of the short message module a1 is input with the low level, so that the short message is sent many times), which represents that the field power supply voltage is abnormally aggravated (such as a fault of a nearby power transformer), and the fault point can be directly cleared by finding the cause on the field.

Fig. 1, 2 and 3 show that this novel optimum combines another set of low-voltage circuit breaker or air switch etc. to use, and another set of low-voltage circuit breaker or air switch can detect control to on-the-spot consumer short circuit and load are too big like this, and this is novel to the consumer input voltage too high or cross low and detect, plays the duplicate protection effect. This is novel in, high low pressure detection circuitry can carry out real-time supervision to the mains voltage height that low voltage circuit breaker body input to consumer, when the voltage is too high or cross low, and the homoenergetic controls divide-shut brake equipment and makes low voltage circuit breaker body tripping operation protection consumer. In this is novel, delay circuit and high-low pressure detection circuitry etc. can control combined floodgate equipment combined floodgate after voltage recovery is normal. This novel tripping operation back SMS module can be automatic for managers propelling movement SMS, and managers can know the on-the-spot power supply condition the very first time, has guaranteed electrical equipment normal work as far as possible, has reduced electrical equipment because of input voltage is too high or low probability of damaging excessively. The resistance of adjustable resistance RP, RP1 need be confirmed during this novel first production, and transformer T primary winding inserts adjustable output voltage's voltage regulator power output end, adjusts voltage regulator output mains voltage 235V earlier, then slowly adjusts adjustable resistance RP's resistance, just adjusts relay K when getting electric, and the resistance value of adjustable resistance just adjusts needs, and among the follow-up practical application, when mains voltage just is higher than 235V, the circuit breaker body will divide the floodgate. Then, the voltage regulator is regulated to output power voltage 198V, then the resistance value of the adjustable resistor RP1 is slowly regulated, the resistance value of the adjustable resistor is regulated to be required when the relay K is just regulated to be powered, and in subsequent practical application, when the power voltage is just lower than 198V, the circuit breaker body can be opened. After the adjustment is finished, the power supply is disconnected, the adjustable resistors RP and RP1 are detached from the circuit, resistance values are measured by using a resistance meter, and the fixed resistors with the same resistance values can be used for replacing the fixed resistors (or directly adjusting the resistance values of the adjustable resistors RP and RP1 in place) in subsequent production without determining the resistance values of the adjustable resistors RP and RP 1. The resistances of the resistors R2 and R R, R3 are 1K, 1.1M and 470K respectively; the model number of the NPN triode Q, Q1 is 9013; relays K, K1, K2 are DC12V relays; the electrolytic capacitors C, C1 and C3 are respectively 470 muF/25V, 20 muF/25V and 100 muF/25V; the VS model of the controlled silicon is MCR 100-1; the adjustable resistors RP, RP1 are 10M in size.
