TM 2000 Universal protection TM 2000-M Universal protection |
I. Overview
TM 2000 digital low-voltage protection device is a current, voltage protection and three-phase reclosing as the basic configuration of the complete set of low-voltage protection device. Suitable for 35KV and below the voltage level of the indirect grounding system or by resistance grounding system in the low-voltage protection, can be installed in the switchgear in situ, can also be installed in the control room panel.
The main function configuration is as follows:
Three - phase phase - to - phase current protection element
Three - stage zero - sequence current protection element
Low voltage latching element
Reclosing elements
Closing acceleration protection element (front acceleration, rear acceleration)
Overload components
Low voltage components
Overvoltage components
PT disconnection detection element
Non - electric components
II. Technical parameters
1. Rated DC voltage: 220V or 110V
2. Rated AC data:
a) Line extraction voltage 100 V or V
b) AC current 5A or 1A (order note)
c) Rated frequency 50Hz
