Transformer with remote switching-on function

Technical Field

Background

A transformer is a widely used electrical device. In order to ensure safe operation, the transformer is provided with a matched high-voltage load isolation power switch besides some monitoring and sampling devices (such as an electric energy meter and a device for monitoring the operation state of the electric energy meter). In practical applications, when a power department maintains a transformer itself, or maintains equipment for supplying power to the transformer, and when an electrical load is too large, a high-voltage load isolation power switch associated with the transformer needs to be turned off, so that a power input end of the transformer is separated from an input high-voltage power supply (generally 10 KV), and then the transformer is maintained or the load of the transformer is temporarily turned off.

At present, in the prior art, the separation and combination of a high-voltage load isolation power switch of a transformer are realized by a power manager, and an operation linkage rod of the high-voltage load isolation power switch is pulled or pushed by an insulating long rod on site, so that the switching-on and switching-off actions of the high-voltage load isolation power switch are realized. Because the manual field operation is needed, not only is the inconvenience brought to the operator, but also the labor cost expenditure of the power management department is increased. When the transformer works abnormally or the load is increased suddenly (the device for monitoring the running state of the existing transformer can transmit the monitored related data such as temperature data, current and the like representing the transformer works abnormally to a remote manager through GPRS (general packet radio service)), because the manager cannot arrive at the site in real time, the transformer can be damaged due to too late switching-off time and too long working abnormal time of the transformer. Based on the above, it is particularly necessary to provide a transformer which not only has the function of realizing the remote switching on and off operation of a matched high-voltage load isolation power switch, but also has the function of realizing the on-site non-contact switching on and off operation.

When the invention is used, when the transformer body works abnormally or suddenly the load is increased (the prior transformer is matched with a device for monitoring the running state, the monitored related data such as temperature data, current and the like representing the working abnormity of the transformer can be transmitted to a remote manager through GPRS in real time), when the manager needs to open the high-voltage load isolation power switch of the transformer body 1, the remote manager operates the application interface of the mobile phone to send a second wireless closing instruction, after receiving the second wireless closing instruction, the remote controller A1 of the mobile phone outputs a high level to enter the positive power input end of the relay K2 (the positive control power input end, the negative control power input end and the negative control power input end of the relay K2 are respectively communicated with the positive and negative poles of the storage battery G2), then the relay K2 is electrified to attract the two control power input ends and the two normally open contact ends of the relay K2, because the negative and positive pole power input ends of the motor reducing mechanism M are respectively connected with the two normally open contact ends of the relay K2, the negative and positive pole power input ends of the motor reducing mechanism M are powered on at the moment, and the subsequent high-voltage load isolation power switch is switched off (after the switching-off is successful, a remote administrator operates the mobile phone application interface to send a second wireless open circuit instruction, after the mobile phone remote controller A1 receives the second wireless open circuit instruction, the 4 th pin of the mobile phone remote controller A1 stops outputting a high level to enter the positive pole power input end of the relay K2, the relay K2 is powered off and does not attract again, and further the negative and positive pole power input ends of the motor reducing mechanism M are powered off).

In practical application, when an electric power manager needs to switch on the spot, for example, under the conditions that a mobile phone is in shortage, a communication network is interrupted (or the field communication network is not good), or the mobile phone with corresponding application software is not brought to the spot, the wireless remote control board A4 can be continuously and effectively used for non-contact control and the switching-on action of the high-voltage load isolation power switch; an operator presses a first transmitting key SK1 of the wireless remote control board A4, the wireless remote control board A4 transmits a first path of wireless closing signal, the wireless receiving circuit module A3 receives the first path of wireless closing signal, then the 4 th pin outputs high level, the high level is subjected to voltage reduction and current limitation through a resistor R5 and enters the base of an NPN triode Q3, the NPN triode Q3 conducts a collector and outputs low level and enters the base of a PNP triode Q5, then the PNP triode Q5 conducts the collector and outputs high level, the high level is conducted through a diode VD, and enters the positive power input end of a relay K1 (the positive control power input end, the negative control power input end and the negative control power input end of the relay K1 are respectively communicated with the positive and negative poles of a storage battery G2), then, the relay K1 is electrified to attract the two control power input ends and two normally open contact ends of the relay K6857 to be respectively closed, because the positive and negative power, then, the positive and negative pole power input ends of the motor reducing mechanism M are powered on, and the subsequent high-voltage load isolation power switch is switched on (after the switch-on is successful, the manager presses the first transmitting button SK1 of the wireless remote control panel A3 again, the wireless remote control panel A3 sends a first path of wireless open-circuit instruction, the wireless receiving circuit module A3 stops outputting a high level to enter the positive pole power input end of the relay K1 after receiving the first path of wireless open-circuit instruction, so that the relay K1 is powered off and is not powered on, and further the positive and negative pole power input ends of the motor reducing mechanism M are powered off).

As shown in fig. 1, 2 and 3, when a manager sends a high-voltage load isolation power switch opening instruction through a mobile phone or a wireless remote control board, a relay K2 is powered on and closed, and a negative and positive two-pole power input end of a motor speed reducing mechanism M is powered on, a power output shaft of the motor speed reducing mechanism M drives a follower rod 12 and four insulating side rods 13 to synchronously rotate clockwise through a flange plate, and then four movable contact joints 7 at the upper parts of the four insulating side rods 13 are respectively pulled out from the front ends of four static contact joints 8 of the high-voltage load isolation power switch; when the follower rod 12 continues to rotate clockwise to be close to 90 degrees (close to 8 seconds), the magnet CT of the '┙' type is positioned at the upper end of the second reed switch GH2 just at the front lower left part along with the clockwise rotation, and under the magnetic action of the magnet CT, two movable contacts and a fixed contact inside the reed switch GH2 are opened; because two wiring ends of the reed switch GH2 are connected in series between the second normally open contact end of the relay K2 and the positive power supply input end of the motor speed reducing mechanism M through a lead, at the moment, the motor speed reducing mechanism M loses power and does not work any more, and the situation that the power output shaft of the motor speed reducing mechanism M rotates too much clockwise and influences the normal work of the whole equipment is prevented. When a manager sends a switching-on instruction of the high-voltage load isolation power switch through a mobile phone or a wireless remote control board, a relay K1 is electrified and sucked, and the positive and negative pole power input ends of the motor speed reducing mechanism M are electrified, the power output shaft of the motor speed reducing mechanism M drives a follower rod 12 and four insulating side rods 13 to synchronously rotate anticlockwise through a flange plate, and then four movable contact connectors 7 on the upper parts of the four insulating side rods 13 rotate anticlockwise and are respectively clamped into the front ends of four static contact connectors 8 of the high-voltage load isolation power switch; when the follower rod 12 continues to rotate clockwise to approach 90 degrees (approaching 8 seconds, the distance between the rear side ends of the four movable contact connectors 7 and the inner rear sides of the front ends of the four static contact connectors 8 is about 0.5 cm at the moment), at the moment, the ┙ -shaped magnet CT rotates anticlockwise, the upper end of the right side part of the original rear part is just positioned at the upper end of the first reed switch GH1, and under the magnetic acting force of the magnet CT, two movable contacts and a static contact in the reed switch GH1 are opened; because two wiring ends of the reed switch GH1 are connected in series between the first normally open contact end of the relay K1 and the positive power supply input end of the motor speed reducing mechanism M through a lead, at the moment, the motor speed reducing mechanism M can lose power and does not work any more, and the influence on the normal work of the whole equipment caused by the fact that the power output shaft of the motor speed reducing mechanism M rotates anticlockwise too much is prevented.

As shown in fig. 3, when the relay K2 is powered on and switched off, the power output from the two normally open contact ends of the relay K2 enters the negative and positive pole power input ends of the motor speed reducing mechanism M, and simultaneously, the positive power also synchronously enters the positive power input end of the electrolytic capacitor C1 through the resistor R1 for voltage reduction and current limitation, so as to charge the electrolytic capacitor C1, and when the electrolytic capacitor C1 is not charged within the first 10 seconds, the base of the NPN triode Q2, after the voltage reduction and current limitation through the resistor R3 and the resistor R1, the voltage obtained from the positive pole of the storage battery G2 is lower than 0.7V, so that the collector of the storage battery is in a cut-off state and has no output, so that the short message module a2 does not work to send a short message; after the charging time reaches about 10 seconds, at the moment, the electrolytic capacitor C1 is fully charged, the base of the NPN triode Q2 is connected with the base of the battery G2 through the resistor R3 and the resistor R1, the voltage obtained from the positive electrode of the battery G2 is higher than 0.7V, and then the collector of the NPN triode Q2 outputs low level to enter the 4 feet of the second trigger signal input end of the short message module A2, so that the short message module A2 can send a prestored short message of 'brake separating success' to the mobile phone of a manager under the action of an internal circuit, the manager can visually know that the brake separating is successful after receiving the short message, if the short message is not received after 10 seconds, the manager can send a second path of wireless closing signals through the mobile phone interface again until receiving the short message, and the operation effectiveness is effectively guaranteed. When the relay K1 is switched on and is electrified and attracted, power output by two normally open contact ends of the relay K1 enters the positive and negative pole power input ends of the motor speed reducing mechanism M, meanwhile, a positive power synchronously enters the positive power input end of the electrolytic capacitor C through the voltage reduction and current limitation of the resistor R to charge the electrolytic capacitor C, and when electricity of the electrolytic capacitor C is not charged within 10 seconds at the beginning, the base electrode of the NPN triode Q1 is subjected to voltage reduction and current limitation through the resistor R and the resistor R2, the voltage obtained from the positive electrode of the storage battery G2 is lower than 0.7V, so that the collector of the storage battery G2 is not output in a cut-off state, and the short message module A2 cannot work to send a short message; after the charging time reaches about 10 seconds, at the moment, the electrolytic capacitor C is fully charged, the base electrode of the NPN triode Q1 is subjected to voltage reduction and current limitation through the resistor R and the resistor R2, the voltage obtained from the positive electrode of the storage battery G2 is higher than 0.7V, so that the base electrode is conducted, further, the collector electrode of the NPN triode Q1 outputs low level to enter the 3 pins of the first trigger signal input end of the short message module, then, under the action of the internal circuit of the short message module A2, the prestored short message of 'successful closing' is sent to the mobile phone of a manager, the manager can visually know the successful closing after receiving the short message, if the short message is not received after 10 seconds, the manager can send a first wireless closing signal through the mobile phone interface again until receiving the short message, and the effectiveness of operation is effectively guaranteed. When the remote switching-on/off device is used, a manager can operate the mobile phone application interface at a remote end and respectively send two paths of control instructions according to needs, so that the remote switching-on/off action is realized; under the action of a hand remote control circuit and the like, no matter the switching-off or the switching-on is successful, the short message circuit can automatically push a corresponding short message to a remote manager, and the manager can timely know whether the switching-on or the switching-off is successful according to the short message information, so that the operation effectiveness of the switching-on and the switching-off is ensured. In the invention, the non-contact switching-on and switching-off actions of the high-voltage load isolation power switch can be effectively controlled through the wireless remote control board and the wireless control circuit on site, so that the wireless remote control board can be continuously and effectively used for the non-contact switching-on and switching-off actions when the wireless remote control board and the high-voltage load isolation power switch are used to achieve the double insurance effect when the mobile phone is in short charge, the communication network is interrupted (or the field communication network is not good) or the mobile phone provided with corresponding application software is not brought to the site during field operation. The invention brings convenience to power management personnel, reduces the labor cost expenditure of a power management department, and can effectively prevent the hidden trouble of damage caused by too late switching-off time and too long abnormal working time of the transformer body when the abnormal working or sudden load increase of the transformer body occurs.
