Description
The present invention relates to a proximity type voice alarm device by measuring the temperature of a power source part, more specifically, by monitoring the temperature change due to deterioration of various electric devices installed inside the housing in real time and informing the manager, To a proximity type live wire and a voice alarm device by a temperature measurement of a power supply part using a single-loop type optical communication device capable of reducing the temperature of the power supply part.
The switchgear is an electric device that is installed and used indoors or outdoors, such as a building or a substation, where a lot of electric power is used, and arranges and manages electric devices such as various switches, instruments, relays (relays), and transformers uniformly. A high-voltage current flows through the interior of the switchboard. The switchboard is electrically connected to various facilities through a busbar that can energize high-voltage currents.
In recent years, as the demand for electric power has increased due to the increase of the facilities due to the increase in the electric power consumption of the industrial site and the increase of the information equipment used in the consumer, the electric power consumers receiving the extra high voltage power, There is an increase in the installation of power distribution systems, which are base power facilities. These faults are installed and operated in various ways, depending on the size of the used voltage, usage, location, etc., such as a high-voltage switchboard, a low-voltage switchboard, an MCC, and a distribution board.
However, it is a reality that various types of electric equipment accidents are occurring due to the increase in installation and capacity of electric power facilities. Particularly, in the interior of a switchgear with a closed structure, thermal deterioration due to the temperature rise of electric devices, electrical deterioration due to electric field concentration, mechanical deterioration due to mechanical stress, and environmental deterioration due to time or place, Is likely to accelerate. And electrical devices where insulation deterioration occurs generate a local discharge (PD). If the local discharge is continuously operated while being left untreated and exceeds the insulation strength limit value of the electric devices, a flash over occurs, thereby causing problems such as breakage of the electric device, fire, power failure, and the like. In addition, when contact resistance increases due to screw loosening or the like at a joint portion of a current path such as a bus bar, heat may be generated and short-circuited parts or parts may melt and lead to fire.
After an incident, recovery takes a lot of time and money. Therefore, before an accident occurs, it is necessary to detect and diagnose an abnormal symptom in advance of the accident. Currently, various monitoring devices and diagnostic devices capable of monitoring and diagnosing signs such as partial discharge and temperature rise, which are insulation deterioration phenomena of electric devices, have been developed. However, research and development Is continuing.
