Description

Electrical Power Protection trainer

Features :

Protection Relay Experiment Trainer:
Experiment projects are complete, experiment content is rich,
design is reasonable, which are beneficial to broaden the
students’ knowledge Experimental device has excellent compatibility
and scalability.
Experimental installations adopt platform design, laboratory
modules using component design Experimental device has
strong intuitionist.
Each relays is the abdomen – installed on the panel surface,
students can clearly see the action of every relay, and are
convenient to set relay values.
At the same time, the relays and other components electrical
diagrams of are painting on each panel, which are complete
and consistent teaching materials, can help students under-
stand the book knowledge, improve the experimental results.
The experiments are strong package, the AC-DC power
supply, instrumentation, relay and experimental connecting
wire in experiment all fully equipped Experiment has
authenticity.
The relays used in experiment are relays which are currently
using on-site power system, and better reflect the status of the
power system, and lay a good foundation to engage in design,
installation, debugging, maintenance and other work to for
students after graduation for protection system Structure is
reasonable.
The whole structure adopt a three-tier structure, panel ranking
according to the actual line with the flow, experimental
function block is clarity, carefully designing improve experimenter’s
understanding of the system, wiring facilitate and the
efficiency of the experiment.
The experiment device has perfect protection measures.
The device provide leakage circuit breakers and other physical
security protection measures. Various instruments and
power supplies all have a perfect protection function.
