Description

Technical Field

[0001] This utility model relates to the field of power equipment measurement technology, and in particular to an integrated detection and protection device for portable lamp power supply. Background Technology

[0002] According to the industry standard DL / T596-2021 "Preventive Testing Procedures for Electrical Equipment," the preventive testing items for hydro-generator rotors include rotor DC resistance, rotor AC impedance, rotor AC withstand voltage, and rotor insulation resistance. Since the generator rotor and other equipment are located indoors, the space is too large, necessitating the use of portable lights for each test. Traditional portable lights have a power of 100W, and their size and weight are excessive, making them difficult to move easily. Furthermore, during preventive testing of hydro-generator rotors, these portable lights cannot promptly trigger alarms or automatic protection in case of excessive current or voltage, posing a safety hazard during the test. Summary of the Invention

[0003] The technical problem this utility model aims to solve is to provide an integrated detection and protection device for portable lamp power supplies. It provides voltage protection for each circuit. When the output voltage or current is too high, the voltage and current detection module detects the data and transmits it to the feedback control module. The feedback control module then sends a circuit disconnection signal to the relay, which disconnects the circuit, thus avoiding safety hazards caused by excessive power and improving the safety of the test. A high-flux inductor is used in the DC-to-AC conversion circuit, greatly reducing the size and weight of the heat sink. This results in a smaller, lighter, and more portable integrated detection and protection device for portable lamp power supplies. The device has a reasonable overall structure, accurate logic, convenient operation, and strong practicality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an integrated detection and protection device for portable lamp power supply, including two output feedback control modules, namely a 12V output feedback control module and a 36V output feedback control module. The 12V output feedback control module is provided with a first display module and a first buzzer. The 12V output feedback control module is connected to the first detection module through a line.

[0005] The 36V output feedback control module is equipped with a second display module and a second buzzer. The 36V output feedback control module is connected to the second detection module via a line.

[0006] In a preferred embodiment, the first detection module includes multiple first detection modules, each of which is equipped with a first relay and a second relay. The first relay and the second relay are respectively connected to the corresponding AC12V portable lamp through a first voltage switching switch and a second voltage switching switch.

[0007] In a preferred embodiment, the second detection module includes multiple second detection modules, each of which is equipped with a third relay and a fourth relay. The third relay and the fourth relay are respectively connected to the corresponding AC36V portable lamp through a third voltage switching switch and a fourth voltage switching switch.

[0008] In a preferred embodiment, fuses are provided at the connection points between the first relay and the second relay and the first voltage switching switch and the second voltage switching switch.

[0009] In a preferred embodiment, fuses are provided at the connection points of the third and fourth relays with the third and fourth voltage switching switches.

[0010] The integrated detection and protection device for portable lamp power supply provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0011] (1) Voltage circuit protection is provided for each circuit. When the output voltage or current is too high, the voltage and current detection module detects the data and transmits it to the feedback control module.

Detailed Implementation

[0017] Example 1:

[0018] like Figure 1 In the present invention, an integrated detection and protection device for a portable lamp power supply includes two output feedback control modules, namely a 12V output feedback control module 1 and a 36V output feedback control module 2. The 12V output feedback control module 1 is provided with a first display module 3 and a first buzzer 4. The 12V output feedback control module 1 is connected to a first detection module 20 through a line.

[0019] The 36V output feedback control module 2 is equipped with a second display module 5 and a second buzzer 6. The 36V output feedback control module 2 is connected to the second detection module 21 via a line.

[0020] In a preferred embodiment, the first detection module 20 includes multiple first detection modules 7, each of which is equipped with a first relay 8 and a second relay 9. The first relay 8 and the second relay 9 are respectively connected to the corresponding AC12V lamp 12 through a first voltage switching switch 10 and a second voltage switching switch 11.

[0021] In a preferred embodiment, the second detection module 21 includes multiple second detection modules 13, each of which is equipped with a third relay 14 and a fourth relay 15. The third relay 14 and the fourth relay 15 are respectively connected to the corresponding AC36V lamp 18 through a third voltage switching switch 16 and a fourth voltage switching switch 17.

[0022] In a preferred embodiment, fuses 19 are provided at the connection points of the first relay 8 and the second relay 9 with the first voltage switching switch 10 and the second voltage switching switch 11.

[0023] In a preferred embodiment, fuses 19 are provided at the connection points of the third relay 14 and the fourth relay 15 with the third voltage switching switch 16 and the fourth voltage switching switch 17.

[0024] Example 2:

[0025] like Figure 1 In this invention, the method of use is as follows: 220V AC power is converted into 10 channels of 24V DC power, then DC power is converted into 10 channels of 12V AC power, 220V AC power is converted into 10 channels of 54V DC power, and then DC power is converted into 10 channels of 36V AC power. When a short circuit occurs at the output port, fuse 19 blows to protect the circuit. When any of the first detection module 7 or the second detection module 13 detects that the current or voltage value exceeds a certain value, the light screen of the corresponding module's display module will show which line is faulty and the buzzer will sound an alarm.

[0026] The beneficial effects of this utility model are as follows: Voltage circuit protection is provided for each circuit. When the output voltage or current is too high, the voltage and current detection module detects the data and transmits it to the feedback control module. The feedback control module sends a circuit disconnection signal to the relay, which disconnects the circuit, avoiding safety hazards caused by excessive power and improving the safety of the test. A high-flux inductor is used in the DC-to-AC circuit, greatly reducing the size and weight of the heat sink, thus making the integrated detection and protection device for the portable lamp power supply smaller, lighter, easier to move, and more portable. The overall structure of the device is reasonable, the logic is accurate, the operation is convenient, and it is highly practical.
