Product Code : EL-HARS-16823
1.
Knowledge of electric components
Various commonly-used electric components are introduced in
detail for teaching purpose including micro circuit breaker, PVPR, timing
relay, auxiliary relay, magnetic contactor, thermal relay, current transformer,
and voltage/current switch with 30 power.
2.
Knowledge of protective equipment
Offering not only the function description and instruction of
the pressure protective switch that is commonly used in chilled water unit is
offered, but also the instruction manual and operational concept about the HLP,
OLP, anti-freeze switch, and temperature switch, etc. The learner can
understand the complete protection measures of chilled water unit.
3. Y-A
manual lower-voltage start control circuit of 30 induction motor
Students can realize the advantages of lower-voltage during
practice and experience the speed change of motor by manual switch. Besides,
students would be more familiar with the usage of relays by adopting other
electric components.
4. Y-Y/Y-A
circuit of chilled water unit
Students can manipulate the Y-Y starting control circuit of
small and middle size chilled water unit as well as the lower-voltage starting
circuit used in units above 7.5HP. They would be more familiar with the usage
condition of various protective switches.
5. Circuit
of chilled water unit
The practice for circuit of chilled water unit is almost the
same as that of the system in industry. Students would grasp full control
concepts about chilled water unit by using the electric components and
protective switches.
6. Pressure
auto-start, manual-start switch circuit, chain circuit practice
Students would gradually familiarize themselves with the
usage of components during the practice of basic chain circuit and switch
circuit. Moreover, they can look into these circuits through designing and
testing the circuit by the manual or pressure-triggered switch.
7.
Forward/reverse rotation control circuit of 3ø induction motor, automatic
forward / reverse rotation cycle control circuit
With the practice of motor control circuit, students become
skilled in motor usage and each electric component; moreover, users can utilize
this equipment to verify their own designed circuit.
