[0001] The utility model relates to the technical field of switch cabinets, in particular to a high and low voltage switch cabinet with a leakage alarm. Background Art

[0002] High and low voltage switchgear, as the name implies, is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations will use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. High and low voltage switchgear is widely used in places such as power transmission, distribution and substations, and plays an important role in power distribution, control, protection and monitoring.

[0003] In the event of a leakage, the leakage protector of a traditional high and low voltage switch cabinet will automatically cut off the power. However, after the power is cut off, there is no circuit support and no lights in the distribution room. The emergency lighting is insufficient and short-lasting, which affects the vision of maintenance personnel. Maintenance personnel need to bring their own lighting equipment, which wastes time looking for leakage switch cabinets and affects maintenance efficiency. Therefore, a high and low voltage switch cabinet with leakage alarm is urgently needed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an embodiment: a high-low voltage switch cabinet with leakage alarm, comprising a high-low voltage switch cabinet 1 and an alarm lighting device 2, the alarm lighting device 2 is fixedly installed on the top of the high-low voltage switch cabinet 1, the alarm lighting device 2 comprises a fixed frame 3, an energy storage power supply 4, a charging lighting lamp 5 and a PLC controller 7, the PLC controller 7 is fixedly installed on the outside of the fixed frame 3, and a sound and light alarm 8 is fixedly installed on the side of the PLC controller 7 away from the fixed frame 3. The activation of the sound and light alarm 8 can assist maintenance personnel to quickly find the position of the leakage high-low voltage switch cabinet 1, the two ends of the energy storage power supply 4 are respectively movably plugged with charging wires 9, and the outer bottom end of the charging lighting lamp 5 is evenly provided with a limited position slide groove 10, and the bottom end of the fixed frame 3 near the PLC controller 7 is symmetrically fixedly connected with two fixed plug-in boards 11, and a charging base 6 is movably plugged on the fixed plug-in board 11, and a limited position slide rod 13 is evenly fixedly connected to the inner side of the top of the charging base 6, and two charging plugs 12 are symmetrically fixedly connected to the top of the charging base 6.

[0022] Auxiliary buckle grooves 14 are symmetrically provided on both sides of the charging base 6, and a fixed plug-in groove 15 is provided at one end of the bottom end of the charging base 6. The fixed plug-in groove 15 and the two auxiliary buckle grooves 14 are vertically cross-arranged, and the fixed plug-in board 11 is movably plugged into the inside of the fixed plug-in groove 15. The auxiliary buckle groove 14 can assist the user to pull the charging base 6 out of the fixed plug-in board 11.

[0023] The end of the charging wire 9 away from the energy storage power supply 4 is movably plugged into the top of the charging base 6, the charging plug 12 is movably plugged into the bottom of the charging lighting lamp 5, and the limiting slide bar 13 is slidably connected to the inner side of the limiting slide groove 10, the charging lighting lamp 5 is electrically connected to the charging base 6 through the charging plug 12, and the charging base 6 is electrically connected to the energy storage power supply 4 through the charging wire 9, so that the charging lighting lamp 5 can be kept fully charged at any time, which is convenient for emergency use by maintenance personnel.

[0024] The PLC controller 7 is electrically connected to the sound and light alarm 8, the charging lighting 5 and the leakage protector inside the high and low voltage switch cabinet 1 respectively. When leakage occurs, the leakage protector cuts off the power and sends an electrical signal to the PLC controller 7. After receiving the power-off signal, the PLC controller 7 can start the preset program to send out an alarm to remind the staff.

[0025] The energy storage power supply 4 is electrically connected to the PLC controller 7, the sound and light alarm 8 and the high and low voltage switch cabinet 1 respectively. Under normal circumstances, the energy storage power supply 4 maintains a charging state. When the power is off, the energy storage power supply 4 can supply power to the PLC controller 7, the sound and light alarm 8 and the charging lighting 5.

[0026] Working principle: During use, first set the control program for the PLC controller 7. When the high and low voltage switch cabinet 1 leaks electricity, the leakage protector in the high and low voltage switch cabinet 1 will automatically cut off the power. When the power is cut off, the PLC controller 7 receives the electrical signal sent by the leakage protector. At this time, the PLC controller 7 controls the sound and light alarm 8 to start the sound and light alarm. At the same time, the PLC controller 7 controls the charging lamp 5 to turn on the light. When the maintenance personnel hear the alarm issued by the sound and light alarm 8 or find a power outage, the maintenance personnel can find the high and low voltage switch cabinet 1 with leakage through the sound and light alarm 8 when they rush to the distribution room. When the indoor light is dim, the maintenance personnel lift the charging lamp 5 upwards through external force until the bottom of the charging lamp 5 is completely separated from the charging lamp. The inside of the base 6 can then increase the brightness through the light of the charging lamp 5, which brings convenience to circuit maintenance. When the charging lamp 5 is out of power, the charging lamp 5 can be plugged into the top of the charging base 6 by external force, and then another charging lamp 5 can be taken out for lighting. When the two charging lamps 5 are out of power or the other charging lamp 5 has other uses, the maintenance personnel can plug the charging lamp 5 into the top of the charging base 6 by external force, and at the same time unplug the charging base 6 from the fixed plug board 11 through the auxiliary buckle groove 14. Since the charging base 6 is electrically connected to the energy storage power supply 4 through the charging wire 9, the charging lamp 5 can turn on the light while charging, which speeds up the maintenance efficiency.
