Ankerui charging pile current limiting protector

Ankerui charging pile current limiting protectorElectrical fire-resistant current limiting protectors can effectively overcome the high short-circuit current and short circuit interruption caused by traditional circuit breakers, air switches, and monitoring equipmentThe drawbacks of long flow time, large arc sparks generated during short circuits, and short service life make it possible to quickly limit short circuit faults in microsecondsControlling short-circuit current to achieve arc extinguishing protection can significantly reduce electrical fire accidents and ensure the safety of personnel and property in the workplace.Electrical fire-resistant current limiting protectors can be widely used in schools, hospitals, shopping malls, hotels, entertainment venues, temples, cultural relics buildings, exhibitionsResidential buildings, warehouses, kindergartens, elderly buildings, collective dormitories, electric vehicle charging stations, rental shopping malls, wholesale markets, and trade marketsLine protection for the main and branch lines at the end of various electric fields such as Class A, B, and C dangerous goods warehouses.

2 Functional Features

Short circuit protection function. The protector monitors the current of the power line in real time, and can achieve fast current limiting within 150 microseconds when a short circuit fault occurs in the lineProtect and emit sound and light alarm signals.

■ Overload protection function. When the current of the protected circuit is overloaded and the overload duration exceeds the action time (3-60 seconds can be set), the protector startsDynamic current limiting protection and sound and light alarm signals.

■ In table over temperature protection function. When the working temperature of the internal components of the protector is too high, the protector implements over temperature current limiting protection and emits an audible and visual alarm signalnumber.

Overvoltage and undervoltage protection function. When the protector detects under voltage or over voltage in the line, it emits an audible and visual alarm signal, which can be pre-set whether or notActivate current limiting protection.

■ Temperature monitoring function for distribution cables. When the temperature of the monitored cable exceeds the alarm set value, the protector emits an audible and visual alarm signal, which can be pre-setWhether to activate current limiting protection.

■ Leakage current monitoring function. When the monitored circuit leakage exceeds the alarm set value, the protector emits an audible and visual alarm signal, which can be pre-set whether or notActivate current limiting protection.

The protector has one RS485 interface, which can send data to the backend monitoring system for remote monitoring. The monitoring backend can be AnkeThe Rui Acrel-6000/B electrical fire monitoring host can also be the Ankerui Acrel-6000 safety electricity management cloud platform, or a third-party monitoring softwareItem or platform.

Ankerui charging pile current limiting protectorThe wiring terminals are shown in the following figure.

In the instrument, the bottom terminal on the left is the strong current connection terminal, Lin is the single-phase AC 220V L line (live wire) incoming terminal, and Lout isThe L line (live line) outgoing terminal of single-phase AC 220V, Nin is the neutral line incoming terminal, and Nout is the neutral line outgoing terminal. The inlet and outlet lines of the protector shouldSelect the appropriate wire diameter based on the rated current of the protector (or its front-end circuit breaker).The top plug-in terminal of the instrument is a weak current signal access terminal, A and B are RS485 communication terminals, and it is recommended to use 1-1.5mm2 Shielded twisted pair cablesconnect, T1、T2 For a temperature sensor signal input terminal, I△1、I△2 The terminal is a residual current transformer signal input terminal. (Note:Communication signal terminal access needs to distinguish between A and B; The temperature input and residual current input signal terminals do not need to distinguish polarity when connected.The typical wiring diagram is shown in the following figure:
