Abstract
The present invention relates to a voltage variation relay protection electric power system safety technology, especially to a voltage variation relay monitoring electric appliance line safety method. The voltage variation relay changes the passive protection modes of various protectors, is small in size and light in weight, is able to determine accidents in a voltage detection mode, and is applicable to the detection of electric appliances, line overload or short in various environments. The voltage variation relay is a relay to perform action when the voltage in the circuit is lower than a safety value, and is widely applied in the electric power system and the electric appliance decompression (voltage decreasing) protection. When the electric appliance line is accidently decompressed, the voltage variation relay is able to detect at the first time, wherein the detected alarm time is 26.629 milliseconds. The voltage variation relay is able to output stable power supply alarm in the condition of highly unstable voltage while detecting the accidents and connect an electric appliance to automatically cut power supply to ensure the safety of the device and the electric appliance line.
Description
Technical field:
The present invention relates to a kind of buckling relay protection power system security technology, particularly a kind of buckling relay monitoring electric appliance circuits safety method.
Background technology:
Electrical equipment or circuit are short-circuited, ground connection, transship, disconnected mutually and time line voltage disappears or be too low, it will electrical equipment or circuit itself are damaged, jeopardize personal safety.Therefore, for electrical equipment and circuit except designing, install, run and strictly hold in terms of maintenance gate of the quality monitoring and technology is closed, to taking precautions against outside possible trouble, also having innovated on prevention and control resist technology, equipment.Substantially having two kinds at the electic protection traditional approach preventing circuit, one is short circuit and overload protection, and one is earth leakage protective；Conventional short-circuit and over loading protected devices mainly have: fuse, high score chopper and thermal overload relay etc..Earth leakage protective, as the term suggests, mainly mould shell RCCB, pulsed earth leakage protective device etc..These facilities have been not suitable with modern production to be needed.
Buckling relay is mainly used in electric power or circuit overload and short-circuit detecting and protection.Buckling relay changes the passive protection mode of various protector.Traditional protection device is that accident is come, and protector is smashed the protected form of the electric wiring obtained, these its huge structure of traditional protection device, heavinesses.After accident, new part will be replaced and just can recover power transmission.Buckling relay small in volume, judgement accident in the way of detecting voltage, it is adaptable to the detection of the electrical equipment of various environment, circuit overload or short circuit.Buckling relay is when electrical equipment or line short decompression, in the case of the voltage of such extremely unstable, it is possible to export stable power supply, for reporting to the police or performing protection operation.It is totally different from conventional electric power protected mode.It plays critical protective effect to electric appliance circuits overload and short circuit in power system.
Summary of the invention:
Buckling relay it be when in circuit, voltage reaches predetermined value and the relay of action.Can be widely applied in power system, electrical equipment decompression (voltage decline) and under-voltage (voltage is little) protection.When electric wiring accident decompression and under-voltage time, buckling relay can detect (detecting that time of fire alarming is 26.629 milliseconds) in the very first time, when reducing due to short circuit reason supply voltage, buckling relay is detecting that accident is simultaneously, in the case of voltage pole instability, output stabilized power source is reported to the police, it is also possible to connects electrical appliance and automatically disconnects with power supply；When supply voltage recovers, power transmission program to be started, by starting button, otherwise electrical appliance can not self start.If not using buckling Control, but direct switch carries out other mode control, pulls open switch the most in time when having a power failure, when supply voltage recovers, and electrical appliance i.e. self start, it is likely to result in accident.
Additionally buckling relay is arranged on appliance circuit, when voltage exceedes certain value, and buckling relay operable automatically, utilize electromagnet suction and the relay cut off the electricity supply, be applied to overload protection (such as protection silicone tube and controllable silicon original paper).
Buckling relay is formed by with lower part:
1. Inspection and monitoring system 2. acousto-optic warning unit 2-1 system luminescence indicating member 3. power control system
4. voltage regulation unit 5. short detection unit 6. controls output circuit 7. buckling relay
8. signal comparison operation unit
