    Three Phases Induction Voltage Regulator Electrical Trainer Vocational Educational Equipment

    SR6123E Three Phases Induction Voltage Regulator Electrical Trainer Vocational Educational Equipment
    1 Introduction
    The three-phase self-coupling voltage regulator is essentially a self-coupling transformer with continuous voltage regulation. There are two types of core – ring and column. The column core is similar to the general transformer, and it is made of silicon steel. The ring core is rolled with a silicon steel strip. 20kVA and the following small capacity self-coupling voltage regulator, more choose ring type iron core; More than 20kVA users adopt column core. In the structure of the ring-type autovoltage regulator, the winding is wrapped in a single layer of insulated copper wire around the ring core. The surface of the coil is polished to a smooth surface, and the brush with the electrochemical graphite is in contact with it. The brush can be used to rotate the surface of the wire to change the output voltage. If the current capacity is greater than 10A, it can be used in parallel with two or more brushes. The self-coupling voltage regulator is generally made from cold and dry. Oil immersion is also used in special occasions with large capacity or special circumstances. Three ring – type single – phase self – coupling voltage regulator can be composed of three – phase self – coupling voltage regulator.

    Overload Relays Trainer Four Pole Educational Equipment For College

    SR6118E Overload Relays Four Pole Educational Equipment For College
    1 Introduction
    Thermal overload relay is the principle of applied electric current heat effect, which is used as the overload relay of the sensitive element, and also known as thermal relay. The so-called electrical thermal sensitive bimetallic strip is made of two kinds of alloy heated by the difference between the two linear expansion coefficients. When heated, bimetallic plates are bent from the high expansion layer (active layer) to the lower expansion layer (passive layer). When the current is too large (exceeding the set value), the element is moved by the “heat”, and the power of the controlled circuit and the protected equipment is cut off by the connected dynamic break contact.
    Thermal overload relay is used for motor overload protection with various types. The thermal overload relay is easy to install and easy to use. It has a complete function and low cost. It has been proved by practice that it can reliably protect the motor, so it has always been an important position.
