Temperature monitoring for electrical wires and electrical connection apparatus
First Claim
1. An electric installation apparatus with means for temperature monitoring and warning in the case of overtemperatures in the electric installation apparatus, and comprising:
- a temperature detection unit comprising at least one temperature sensor, a wake-up trigger, and a power switch, wherein the wake-up trigger is configured to be activated by the temperature detection unit to control the power switch in the case of an overtemperature, and wherein the power switch is configured to energize a warning unit;
means for converting a temperature detection signal generated by said temperature detection unit, into a digital signal for processing in a microcontroller, which is adapted to control an RF transmitter for wireless signalling to a remote central block; and
said central block serving for registration of the activity of the warning unit and for activation of mechanisms for preventing further temperature increase or consequences of the temperature already detected or registered,wherein said temperature detection unit, said converting means, said microcontroller and said RF transmitter being all located within the confines of the apparatus.

Abstract
Monitoring apparatus (100, 200, 300) for registration and warning of overtemperature, particularly in connection with harmful heat development in electric installations, as for example outlets, switches and fuse equipment. The apparatus provides for timely warning of heat development, so that overheating and damage is avoided, whereby the operation of electric installation equipment for mounting in electric installations, will have a significantly improved safety. The temperature registration is performed in a unit (100) by means of a sensor (1) which provides an electrical magnitude that is influenced by the temperature, for example a thermistor, which is a temperature-dependent resistor. When a low current is applied to such a component, it will result in a temperature-dependent voltage drop that is measured and gives a direct measure of the temperature. If the temperature exceeds a given value, an alarm unit (200) is activated, and this is turn can provide for remote warning of a central block or plant (300).
