I Product Name: protection device of switchgear
II Mode WZB-2600-3000
III Application
Our WZB-2600-3000 series protection device of switchgear is extensively applicable to the electric power, water conservancy, industrial and other aspects’ establishment and reformation engineering of the transformer substation and distribution of voltage class 110 KV or below.
IV Feature
l New-model hardware technology: Adopting high performance embedded micro-processer, focusing the control function of the single chip (MCU) and the calculating function of the digital signal controller (DSP) as well as data taking in and putting out function, the calculating ability is improved promptly.
l platform of the software and hardware: Generalized, modularized, flexible and configurative hardware can reduce the quantity of the hardware variety, the spare parts and components for the user and can lighten the workload of the software and the on site measurement, which improves the reliability of the software, the hardware and the equipment.
l anti-interference design: Adopt multi-layer printed plate, surface sticking technic and strict isolation between heavy current and light current to reach the high standard EMC.
l easy operation: Convenient, friendly and humanized human-machine interface (large Chinese LCD) and operating mode, with unified and generalized software platform, are convenient for the user to understand and master each different protection unit.
l perfect protection function: Each type is of complete protection function, with perfect auxiliary functions, such as PT circuit break warning, control loop opening warning, device fault warning and anti-trip function which can be set according to the requirement from the user.
l protection intelligentized: Protection trip operation and intelligentized record, which are helpful for the relay protection staff and the operating staff to correctly analyze and judge the reason of the trouble.
l massive communication function: Supplies standard communication interface which can fulfil remote measurement, remote signalling, remote control and sequent accident record (SOE) and other functions.
l enhanced design of the cabinet body: Adopting enclosed, enhanced unit crate with high anti-interference ability design, which is adapt to harsh environment.
