Summary of the invention
The purpose of this utility model is to provide a kind of design science, stable performance, safe and reliable, practical multifunctional low-voltage distribution is installed synthetic training apparatus, makes the student carry out low-voltage distribution installation, distribution, debugging under true environment.Drill on equipment, and operate according to actual low-voltage distribution step.
for achieving the above object, the utility model adopts following technical scheme: a kind of multifunctional low-voltage distribution is installed synthetic training apparatus, comprise cabinet body frame, front instrument door is housed on cabinet body frame, the Qianmen, rear instrument door and back door, on front instrument door, reometer is housed, voltage table, power factor meter, Intelligent Reactive Compensation Controller and electric capacity pilot lamp, dispose before cabinet multifunctional mesh orifice plate after training module and cabinet in cabinet, two motor and three capacitors are housed on the bottom of cabinet bulk crossbeam, the Motor Control button is housed on the Qianmen, described motor, one is clockwise and anticlockwise motor, one is star triangular form starter motor, residual current action breaker and residual current circuit breaker are housed after cabinet, busbar is housed after cabinet.
Described cabinet body frame adopts GGD cabinet type, bilateral structure.
Training module has five before described cabinet, and single-phase measurement loop, reactive-load compensation loop, motor forward/backward rotation loop and motor star triangle start loop are housed respectively, on training module, connection terminal is housed before each cabinet.
Safety head is arranged on connection terminal.
On training module, wire casing is arranged before described cabinet.
After described cabinet, the multifunctional mesh orifice plate has three.
The technical scheme that the utility model adopts for solution rural power staff skills training has the following advantages and improves with existing comparing with the technology about the low-voltage distribution installation that once had:
First, because the utility model disposes intelligent reactive power compensating controller and capacitor, form a control of reactive power compensating loop by other components and parts, like this and motor control loop, the single-phase measurement loop, three-phase and four-line dress table connects electric loop and consists of a system, can realize auto-reactive compensation according to power factor when system moves; So not only can carry out single electric loop training to the student, also can give training whole distribution system principle, train wider.
The second, adopt training module of a plurality of module compositions, the electric loop components and parts arrange near actual production, like this to after student training, student's technical ability obtains promoting very soon, better puts into production, and on module, wire casing is housed in addition, guarantees that distribution is attractive in appearance.
The 3rd, cabinet configuration residual current action breaker and residual current circuit breaker, after student's distribution is completed, but errorless power transmission debugging on inspection, when break down in the loop, residual current action breaker and residual current circuit breaker interoperation.Solved other equipment can only distribution can not power transmission technical matters.
