The goal of designing an embankment with insulated berm in permafrost regions is to avoid the lateral thermal-erosion of the embankment slopes,to prevent the permafrost table decline and to keep the nearby environment from degrading.

The temperature protection s incorrect trip in auxiliary equipment system of the thermal power plant often happens for the sudden changing of the temperature measurement value.

At present, temperature protection is used in small capacity single-phase motor.

The discourse presents an improvement of the band-gap voltage reference s circuit design, which integrates with the thought of the temperature protection and the curvature compensation that employs the current feature of MOS device in the sub-threshold region.

the module supports the temperature protection and the short circuit protection effectively, and g.

In addition to that, the module supports the temperature protection and the short circuit protection effectiv.

A simple CMOS thermal-shutdown circuit;

A thermal-shutdown circuit is designed and fabricated using 0.

A 1W white LED constant-current driver with thermal-shutdown function is designed and fabricated with 0.

Three means of protection,that are intimately connected with the gas turbine,namely: combustion supervision,protection against overheating and flame extinguishment,are described in detail,according to the logic chart and its actual behaviour of the MPCP1-M701 single shaft combined cycle unit s turbine protection system.
