Limiting structures 3 are respectively installed on the left and right sides of the housing 1. An upper housing 2 and a lower housing 4 are respectively provided on the upper and lower sides of the housing, and the upper housing 2 and the lower housing 4 are interlocked with each other.
[0025] like Figure 2 As shown, in this embodiment of the invention, a mounting plate 5 is fixed inside the housing 1 by bolts. A line positioning cylinder 9 is installed on the left side of the mounting plate 5. An energy storage capacitor 6, a current limiting protector 7, a polarity protector 8, a controller 10, and a MOSFET transistor 11 are installed on the upper side of the mounting plate 5. The polarity protector 8 is connected to the current limiting protector 7. The current limiting protector 7 is connected to the energy storage capacitor 6 and the controller 10 respectively. The energy storage capacitor 6 is connected to the controller 10 and the MOSFET transistor 11 respectively.
[0026] Among them, the energy storage capacitor 6 is an RFM3.1-685-20S high voltage high power resonant capacitor; the current limiting protector 7 is HX-CH220V / 10A; the polarity protector 8 is FR015L3EZ; and the controller 10 is a PM865K01 controller.
[0027] like Figure 3As shown, the line positioning cylinder 9 provided in this embodiment of the invention has a cylinder body. An upper fixing plate 14 is fixed to the upper side of the cylinder body by bolts, and a rubber base plate 12 is fixed to the lower side of the cylinder body by bolts. A through hole 13 is provided inside the cylinder body. A threaded rod is fixed to the cylinder body and the upper fixing plate 14 through a threaded hole. A compression rubber disc 15 is installed at the bottom end of the threaded rod, and a rotating disc 16 is welded to the outer end of the threaded rod. A rectangular groove is provided on the rotating disc 16 to facilitate its rotation. The connecting line is passed through the through hole 13, and the connecting line is compressed and fixed by the compression rubber disc 15.
[0028] like Figure 4 As shown, the limiting structure 3 provided in this embodiment of the invention is provided with a positioning plug-in block 18, a threaded hole 19 on the positioning plug-in block 18, and an outer plate 17 welded to the outer side of the positioning plug-in block 18.

Its energy storage voltage is 24VDC, the maximum energy storage current is less than 0.36A, and the energy storage time is 5-10 minutes, so it will not adversely affect the main unit. The instantaneous protection power supply is in hot standby mode. When the external grid voltage drops instantaneously, causing the 24VDC power supply to fall below 18-20VDC, the external voltage value is transmitted to controller 10. Controller 10 controls energy storage capacitor 6, current limiting protector 7, and polarity protector 8 respectively to automatically compensate for the voltage drop. The maximum compensation current can reach 30A, ensuring the normal operation of the equipment controller 10 and all components, thereby guaranteeing the normal operation of the equipment.
