1. Overview.
ARB6 series arc protection device integrates protection, measurement, monitoring, control, communication, fault recording, event recording and other functions, which can monitor the arc signal in real time, protect current or voltage increment, and can quickly cut off 04kV 35kV medium and low voltage power distribution system arc light fault.
The ARB6 series arc protection device hardware adopts an integrated design (the device integrates a power module, a CPU module, an arc acquisition module, a current and voltage acquisition module, an open-in and out-exit module, a communication module, a human-machine interface module, etc.), which can realize the direct acquisition and direct control mode, so as to save a lot of time for signal processing and signal transmission and exchange between devices, so as to better meet the requirements of rapidity and reliability of arc protectionThe device software is equipped with a special protection algorithm, with strong anti-interference performance, high reliability, and flexible protection implementation mode, which can be used with ACREL-2000 power monitoring system to provide guarantee for the safe and reliable operation of the power system.
ARB6 series arc protection devices are easy to operate, rich in resources, stable and reliable, and easy to maintain, and are widely used in electric power, water conservancy, transportation, industry, mining, new energy, ships, buildings and other industries.
2. Product introduction
2.1 Product model.
The ARB6 series arc protection is mainly composed of ARB6 arc protection device, ARB-S arc probe and arc plastic optical fiber.
2.2 Product Features.
Note: This feature is available, and it is optional.
2.3. Product selection.
3. Product size
3.1 ARB6 arc protection device installation position and opening size.
When installing the ARB6 arc light protection device, it is necessary to consider the installation space of the switch cabinet, connect with the TA loop of the power supply inlet circuit within the protection range, and connect the protection trip loop, in principle, the nearest installation method is adopted to avoid the connection of the TA collection loop and the trip loop is too long, and it is generally installed on the door of the inlet cabinet or TV cabinet on the medium and low voltage side of the main transformer, and it is recommended to use the panel opening for installation.
The shape and opening size of the ARB6 arc protection device are as follows. (Size unit: mm).
3.2 ARB-S arc probe fixing method and opening size.
The ARB-S arc probe is fixed on the snap bracket, which needs to be installed with an open hole. The cut-out size of the snap bracket is 20 mm (diameter).
Probe mounting location.
4.1. Installation of arc probe in the busbar.
4.2. Arc probe installation in the trolley chamber
4.3. Cable chamber arc probe installation.
