Description

Technical Field

[0001] The invention relates to the technical field of circuit breaker opening and closing power supply, and in particular to a circuit breaker power supply device on a distribution column. Background Art

[0002] The design principle of the power supply device of the circuit breaker on the distribution pole is that when the circuit breaker leaves the factory, the body is only equipped with an emergency opening pull ring of the circuit breaker, and no closing pull ring is set. When the circuit breaker is closed in an emergency, it only relies on the closing button of the circuit breaker terminal to close the circuit. When the circuit breaker terminal circuit board, capacitor, battery, main control panel module and parts fail, emergency power supply and closing are often impossible, resulting in an increase in the power outage time. In addition, the operating voltages of pole-mounted circuit breakers from different manufacturers are different, and different operating voltages need to be provided.

[0003] Existing circuit breakers need to be equipped with different operating voltages according to their models, which is very inconvenient for maintenance and inspection. Maintenance personnel need to match different operating voltages according to the circuit breakers on site, which brings inconvenience to the emergency power supply of the circuit breaker. When the circuit breaker terminal circuit board, capacitor, battery, main control panel module and parts fail, emergency power supply cannot be performed, resulting in increased power outage time.

[0004] Therefore, there is an urgent need for a multi-voltage permanent magnet switch power transmission device to meet the emergency power transmission needs of different circuit breakers. Summary of the invention

[0057] according to Figure 4 As shown, the design of the control panel 2 takes into account the convenience and functionality of operation.

[0058] The power module 3 includes a battery module 31, and the battery module 31 includes a switching power supply 311, a battery 312 and an inverter 313. The input end of the switching power supply 311 is connected to the power line, the output end of the switching power supply 311 is connected to the battery 312, the output end of the battery 312 is connected to the inverter 313, and the output end of the inverter 313 is connected to the adjustable voltage rectifier 5.

[0059] The power module 3 is provided with a first relay 11 , a normally open contact of the first relay 11 is provided on the power line, and a normally closed contact of the first relay 11 is provided on the output line of the inverter 313 .

[0060] The power supply module 3 further includes a power generation module 12 . The power generation module 12 uses a hand-cranked generator. The output end of the hand-cranked generator is connected to the adjustable voltage rectifier 5 .

[0061] The normally closed contact of the first relay 11 and the normally open contact of the second relay 9 form a power supply locking circuit.

[0062] like Figure 1 As shown, in this embodiment, the power module 3 is composed of multiple sub-modules to ensure the stability and diversity of power supply. The battery module 31 includes a switching power supply 311, a battery 312 and an inverter 313.

The power generation module 12 uses a hand-cranked generator to provide emergency power support, and its output end is connected to the adjustable voltage rectifier 5.

[0063] Furthermore, the closing and opening control module 4 includes a closing switch 41 and an opening switch 42, and the locking module 7 includes a second relay 9 and a third relay 10, the closing switch 41 is connected to the second relay 9, the opening switch 42 is connected to the third relay 10, the normally open contact of the second relay 9 is connected to the normally closed contact of the third relay 10, and the normally closed contact of the second relay 9 is connected to the normally open contact of the third relay 10.

[0064] according to Figure 1 As shown, the closing and opening control module 4 realizes the operation of the circuit breaker through the relay. The closing switch 41 and the opening switch 42 are respectively connected to the second relay 9 and the third relay 10 to form an interlocking mechanism to ensure that the closing and opening actions are not triggered at the same time. The relay contact combination in the locking module 7 forms a power supply locking circuit, which further improves the safety of the system.

[0065] Furthermore, the discharge module 8 includes a fourth relay 81, a discharge button 82 and a discharge resistor 83, the fourth relay 81 is a normally closed contact, the discharge button 82 and the normally closed contacts of the fourth relay 81 are connected to the output end of the energy storage module 6, the output end of the discharge button 82 and the normally closed contact of the second relay 9 are connected to the two ends of the discharge resistor 83, and the discharge resistor 83 is a 100W discharge resistor.

[0066] according to Figure 1 As shown, the discharge module 8 is designed to safely release the energy in the energy storage module 6.

After pressing the discharge button 82, the current is released through the discharge resistor 83 to ensure the safety of the system during maintenance or failure. The power of the discharge resistor 83 is 100W, which can effectively absorb and release excess electrical energy.

[0067] The energy storage module 6 is a 250V / 47000 microfarad energy storage capacitor. The energy storage module is a physical secondary power supply with electricity storage capacity. The energy storage module can provide pulse power. The energy storage module provides energy for the permanent magnet operating mechanism to move and provides a large discharge current for opening and closing the switch.

[0070] The specific implementation process of the power transmission device of the circuit breaker on the distribution column of the present invention is as follows: when the operating voltage of the control box is 110 volts DC, the voltage of the adjustable voltage rectifier 5 is adjusted to 110 volts DC. When the mains is connected, the power supply KM coil is energized, the normally open contact of KM1 is closed, and the normally closed contact is disconnected. The input of the adjustable voltage rectifier 5 is energized and starts to work, and at the same time, the AC 220 volt mains is prevented from reversely entering the inverter 313. When there is no mains access, the power supply KM coil loses power, the normally open contact of KM1 is disconnected, and the normally closed contact is disconnected. The closed contact is closed, and the UPS or battery 312 is inverted into AC 220V through the inverter 313, which is rectified and regulated to DC 110V by the adjustable voltage rectifier 5, and enters the energy storage capacitor to store energy. When the battery 312 has no power, an external hand-cranked generator can be connected to provide energy for the device. At the same time, the relay KM4 coil is energized, and the normally closed contact of the KM4 coil is converted into a normally open contact. When the work stops, the relay KM4 coil loses power, and the energy storage capacitor discharges through the discharge resistor 83.

[0071] When the closing button 26 is pressed, the KM2 coil is energized, the KM2 normally open contact closes, the KM2 normally closed contact is disconnected, and the permanent magnet circuit breaker closing and opening coil 14 obtains a negative and positive operating voltage. When the opening button 27 is pressed, the KM3 coil is energized, the KM3 normally open contact closes, the normally closed contact is disconnected, and the permanent magnet circuit breaker closing and opening coil 14 obtains a positive and negative operating voltage. The normally closed contacts of KM2 and KM3 are interlocked to prevent the closing button 26 and the opening button 27 from being pressed at the same time, which may cause danger.
