Non-recoverable linear temperature sensing detector and its breaking alarming method

Abstract

This invention discloses one in-restorable linear temperature detector and its shortcut alarm method, which comprises linear temperature detect element and its switch case and terminal resistance on both ends of the detection parts, wherein, the linear temperature sensor element is composed of two pieces of detection conductors and NTC isolation layer in between with at least one conductor is easy to be fused wires. This invention provides the method can send different alarm signals according to the shortcut fault or break fire.

Description

technical field

[0001] The invention relates to a linear temperature-sensing detector and a circuit breaking alarm method thereof, in particular to a non-recoverable linear temperature-sensing detector and a circuit breaking alarm method thereof. Background technique

[0002] The linear temperature sensing detector is a widely used fire detector at present. It usually consists of a linear temperature sensing element and one end connected to the linear temperature sensing element. Value) for detection, and according to the size or change rate of the alarm electric parameter (or sampled value) of the conversion box that outputs the fire alarm signal, the other end of the line-type temperature sensing element can be open or connected to a sensor that can activate under normal conditions Terminal resistance for open circuit monitoring, and according to the structure of the linear temperature sensing element, it is divided into two types: recovery type and non-recovery type.
