Description

The ERL150 bench allows the complete study of a production chain of electrical energy by wind turbine.

The unit includes a standard wind turbine linked to an AC motor. The unit is set up on a movable frame protected with transparent guard. The connection to the main unit uses a quick connection plug. The control and production system is an independent module. It includes the general electrical panel, batteries, the production chain components (controller, inverter) and the dissipation elements (lamps, fan).

Students will initially be familiar with the different elements of the installation and electrically connect all the components. After validation by the teacher, they can activate the system and measure the operating parameters with the instrumentation in place. They will then have to vary the conditions (rotational speed of the wind turbine) and calculate the power generated and the different efficiencies.

The bench is autonomous and requires a power supply 230VAC single phase + neutral. The modules are mounted on screwed chassis of anodized aluminum profile (dimensions 45x45mm) equipped with directional castors with brake (diameter 100mm).

The robust design of this equipment makes it perfectly suited for use in schools

The bench includes at least the following:

A wind turbine module including a motor (B) with variable speed with control by a potentiometer and a wind turbine (A) of brand Silentwind (24VDC-400W).

The motor and the wind turbine are coupled directly to simulate rotation. The frame is equipped with 4 directional casters with brakes.

A the production and storage module of energy (C) including:

-the supply electrical box of the machine comprising standard safety devices (lockable disconnect switch, differential circuit breaker, magneto thermal circuit breaker, emergency stop ...)

-a quick connector Harting type for electrical connection between the wind turbine and this module

-Two Batteries in series to store energy (24VDC / 55Ah) with protective bins

-a charge controller

-a inverter (24VDC / 230VAC-500W)

-a emergency charger for the battery

-a charge area 24VDC comprising two lamps and a fan

-a charge area 230VAC comprising two lamps and a fan

So that the system is electrically connected by the students in complete safety, each electrical terminal of each component is reduced on the front panel on a dual socket sink.

The dual sink cords needed to connect are provided.

The bench is supplied with the following instrumentation:

-a rotational speed sensor for the motor (speed of the wind turbine)

-a mobile multimeter with AC/DC clamp ammeter to measure the voltages and currents at the terminals of various elements
