In order to ensure the safe operation of the frequency converter and avoid load impact, the following points must be taken into account: first, try to ensure that the frequency converter has sufficient acceleration and deceleration time. When the frequency converter is turned on or accelerated, it has a soft start function; When shutting down or decelerating, it has a soft shutdown function. Within the allowable range of the equipment, try to increase the acceleration and deceleration time as much as possible. When the device requires a shorter acceleration and deceleration time, the frequency converter should take the following measures: the acceleration and deceleration time is determined by the capacity and load of the frequency converter. The heavier the load, the smaller the capacity of the frequency converter, and the longer the acceleration and deceleration time should be set. The shortest acceleration and deceleration time is determined by the capacity of the frequency converter. If the surge current exceeds the rated current of the frequency converter within the allowed time during operation, the capacity of the frequency converter must be increased.

The OD network 2-in-1 lightning arrester is developed and designed based on national and industry lightning protection standards, as well as the company's years of lightning protection design experience. It adopts an integrated surge protection design for the power supply and network transmission of cameras used in monitoring systems, balancing the potential of various lines. Can effectively prevent lightning surges from inducing overvoltage and damaging equipment in power and network twisted pair cables; Integrated design, reasonable layout, convenient wiring, overall aesthetics, and strong practicality. The rail type network two in one lightning protection device is an integrated multifunctional surge protector. The product is installed in a 35mm rail type, with a small volume and compact appearance, especially suitable for places without installation space. It has beautiful appearance, excellent product performance, fast transmission speed, and can provide lightning protection for camera power+network signals, or POE cameras separately. It is mainly protected through power lines (220V, 24V, 12V+RJ45 network lines)

From a technical principle analysis, there is also a technical misconception that leakage protectors may cause refusal to operate. When the neutral wire is repeatedly grounded, it will cause the leakage protector to shunt and refuse to operate, and it is difficult to find the neutral wire's repeated grounding point. When the power supply is out of phase and the missing phase happens to be the working power supply of the leakage protector, it will cause refusal to operate. Finally, two special points need to be pointed out: 1. When a single-phase electric shock accident occurs (which is more likely to occur in electric shock accidents), that is, when a phase wire (live wire) is in contact with the load side of the leakage protector, it can provide good protection. If insulated from the ground, the leakage protector cannot provide protection when touching one phase wire and one neutral wire.
