ZE3104D Training Bench for Neutral Study engineering educational equipment Electrical Laboratory Equipment

1. Product overview

1.1 Overview

It can through training, let students be familiar with various electric accident reasons so as to prevent electric accident occur. Through learning, students will learn of how the accident occurs, and take cautions on electric accident, so as to enhance the ability of prevent accident, solve electric accidents. Students can learn many safety protection mode in the trainer. 

1.2 Feature

(1)Training module use aluminum column, testing measures, inner integrated training power box. It is easy to use, and it is not easy to be broken.

(2)Modular structure: it has many modules, and it can achieve many training projects, please see the experiment list later.

(3)It has good safety protection system, all the electric terminals select safety plug terminals, the whole set can be connected to ground, if there is electric leakage occurs, students can cut off power immediately, so as to protect themselves.

The bench must allow the study and simulation of different schemas of connections TT, TN (TN-C, TN-S) and IT, must be equipped with protection accessories for each connection, it must allow:

– faults simulation like insulation faults with possibility to adjust insulation resistance and contact resistance

– influence of ground socket quality

– short-circuit fault simulation, between phase and neutral, between 2 phases and simulation of first and second fault (TN and IT)

– verify security limits such as wires maximal length (TN and IT)

– bring to light the chronometric and amperemetric selectivity.

Protection accessories must be industrial type.

     The bench must be delivered totally equipped and functional
