Description
Technical Field
The invention relates to the field of fire monitoring and detection, in particular to an electric fire monitoring detector structure.
Background
The main causes of electrical fires are electrical shorts, including interphase shorts and single-phase ground shorts. The interphase short circuit can generally generate larger short circuit current, so that the overcurrent protection device acts to cut off the power supply in time, and therefore, electric fire disasters are less caused. Single-phase ground shorts can be categorized into metallic shorts and arcing shorts. The risk of the metallic short circuit to fire is not great, and the overcurrent protection device cuts off the power supply in time under the action of the short circuit current mainly because of the great short circuit current. The arc short circuit is not melted due to poor contact at the fault point, and an arc or spark is generated. The circuit breaker is difficult to operate because of the large impedance of the fault point where the arc short circuit occurs, so that the arc continuously exists. It was found that an arc temperature slightly above 0.5A current was as high as 2-3,000 ℃ and could ignite any combustible, and that an arc maintained at a voltage as low as 20V resulted in a continuous and stable arc. Therefore, an arc in which an arc short circuit occurs often becomes an ignition source for an electrical fire.
The electric fire monitoring detector can detect dangerous parameters such as residual current and temperature in an electric circuit, sends out an audible and visual alarm signal according to a set alarm value, and forms an electric fire monitoring system with electric fire monitoring equipment through a communication network. The electrical fire monitoring detector comprises residual current detection and temperature detection. The electric fire monitoring detector and the electric fire monitoring equipment can form different electric fire monitoring systems so as to adapt to the requirements of different occasions, different capacities and different customers.
However, the current electrical fire monitoring detectors on the market currently have the following disadvantages: (1) For the indoor installation, besides the electric fire monitoring detector, a box is additionally arranged to ensure the safety of the wiring terminal, so that the purchase cost of a user is high. (2) For outdoor installation, a case is also required to be additionally arranged to ensure the safety of the wiring terminal and the problems of water resistance and sun protection, so that the purchase cost of users is high.
In order to solve the problems, we have invented an electric fire monitoring detector structure.
