Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as figure 1 As shown, a soft starter thyristor intelligent module includes two thyristors 1 and two radiators 2, W=K*Q*T / β

[0023] Among them: W: the weight of the radiator; K: the reliability factor; Q: the heating power of the thyristor; T: the time for the thyristor to complete when the motor is started; β: the specific heat capacity of the radiator;

[0024] The weight of the heat sink is calculated from the above formula, and then the two thyristor chips are connected in reverse parallel and directly crimped together according to the required shape. A temperature sensor 3 is arranged between the two radiators, and the temperature sensor is used to send the collected temperature signal to the intelligent temperature control protection circuit 4, and the intelligent temperature control protection...

Abstract

The invention relates to the manufacturing technical field of a motor soft starter, and particularly to a soft starter thyristor intelligent module. The soft starter thyristor intelligent module comprises two thyristors and two radiators, wherein the two thyristors are connected in an anti-parallel manner and are crimped between the two radiators; a temperature sensor is arranged between the two radiators; the temperature sensor is used for sending a collected temperature signal to an intelligent temperature control protection circuit; the intelligent temperature control protection circuit is used for collecting the temperature signal information and controlling the operation of the thyristors; the radiators can satisfy the radiating requirements of the operation; meanwhile, the thyristors and the thyristors are packaged in one insulating shell; the radiators are directly and externally connected with a power terminal and a control terminal; the two radiators are connected with electromagnetically-controlled mechanical contacts; and the intelligent temperature control protection circuit controls the actions of the electromagnetically-controlled mechanical contacts through electromagnetic coils on the electromagnetically-controlled mechanical contacts. By adoption of the soft starter thyristor intelligent module, the thermal resistance of the thyristors is reduced, the reliability of the product is improved, and the cost of the product is lowered.

Description

technical field [0001] The invention relates to the technical field of motor soft starter manufacturing, in particular to a soft starter thyristor intelligent module. Background technique [0002] The traditional soft starter is to purchase ready-made thyristor modules or pie-type thyristors, and then add a radiator to form a soft starter power module. Then, the starting voltage of the motor is controlled by controlling the conduction angle of the thyristor through the control circuit, so that the motor can start under the starting condition of soft torque, which has achieved the reduction of the impact of the motor on the power grid. The traditional thyristor belongs to the general structure. For the soft starter, the thyristor shell can be completely removed. The temperature control of the thyristor of the traditional soft starter is not intelligent. The temperature sensor is far away from the thyristor chip, and the temperature control accuracy is not enough. It is set a...
