Description

The thyristor module of built-in temperature sensor
Technical field
The utility model relates to the thyristor module in electronic devices and components field, particularly a kind of built-in temperature sensor.
Background technology
Thyristor, it is thyratron transistor, characteristic with silicon rectification device can work under high voltage, big current condition, and its course of work can be controlled, be widely used in the electronic circuits such as controlled rectification, AC voltage adjusting, contactless electronic beam switch, inversion and frequency conversion.
Thyristor module comprises one or more thyristor elements, and wherein the thyristor junction temperature has bigger influence to the operating characteristic of thyristor, and the accurate measurement of thyristor junction temperature can further guarantee the reliably working of thyristor module.At the thermometric mode of thyristor module junction temperature, all be mounting temperature sensor on the radiator that thyristor module is installed generally at present, there is following shortcoming in this kind mode:
1) if the contact-making surface of thyristor module because the mistake of mounting means or the quality problems of radiator, cause thyristor module and radiator not to have good heat transfer to contact, temperature sensor and thyristor module apart from length, this all will cause temperature measurement data inaccurate, burn to such an extent as to thyristor module is overheated.
2) the thermometric accuracy is not high, and the thyristor junction temperature is at first passed to radiator and passed to temperature sensor by radiator again, and heat has bigger loss by repeatedly transmitting, and causes probe temperature and the junction temperature of reality that big gap is arranged
The utility model content
The utility model provides a kind of thyristor module of built-in temperature sensor for solving the problems of the technologies described above, and can effectively solve the overheated problem of being burnt of thyristor module, can also improve the thermometric accuracy.
The technical solution of the utility model is as follows:
The thyristor module of built-in temperature sensor, comprise thyristor chip, busbar and cover plate, shell, base plate, thyristor chip and busbar are packaged in the space of cover plate, shell and base plate formation, it is characterized in that: the outside of described busbar is close to and is provided with temperature sensor, and described temperature sensor can be arranged at the outside of any one busbar or be arranged at the outside of each busbar.
Described busbar and temperature sensor are combined closely by soldering processes.
Described temperature sensor is connected to the pin of shell by lead-in wire.
The beneficial effects of the utility model are as follows:
The utility model has improved the reliability to the thyristor temperature protection, has solved because thyristor and radiator are installed improperly, and causes the thyristor temperature protection to lose efficacy, and is also overheated and burn with regard to having avoided thyristor module; Improved the precision to the thyristor junction temperature measurement, temperature sensor is directly installed on conducting copper, only through once heat transmission, directly measures the thyristor junction temperature, can think to record the approximate thyristor junction temperature of temperature; Improved the ease for use of thyristor module, simplified the use of thyristor module and installed.
