Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus bar having a streamlined concavo-convex structure, and more particularly, to a bus bar having a streamlined concave-convex structure for reducing the heat of a bus bar through which a current flows through a streamlined process.
Generally, the bus bar is installed between the main breaker and the branch breaker, and is usually constructed of a bus bar connected to the main breaker, and a charger booth connected to the bus bar and capable of receiving power supplied from the main breaker. The busbars and the charger busbars are constructed to be mutually connected through rivets or the like. In addition, a major advantage of bus bars is that they are more suitable for modern high capacity transmission systems because they can deliver more electrical energy with the same volume of conductors than cables, which is safer and less energy intensive.
Meanwhile, Korean Patent No. 10-0921965 discloses a technique for converting an extra-high voltage electricity supplied from a power supply source into a low voltage and a rated capacity suitable for a variety of facilities and equipments to be used, (PTC) when the temperature of the booth bar reaches a certain temperature (T1), and a reference temperature for allowing the user to set the temperature of the booth bar A temperature detection sensor provided between the top surface of the insulator and the bottom surface of the joint portion of the bus bar to detect the temperature of the bus bar in real time, a temperature sensor for converting the temperature of the bus bar detected by the analog signal into a digital signal If the temperature of the bus bar inputted through the A / D converter is higher than the set temperature set by the user, the PTC And a timer for supplying a driving voltage to the PTC only for a predetermined time when the PTC driving signal is output from the microcomputer, wherein the timer controls the driving of the thermoelectric element in response to the output signal of the microcomputer. The PTC drive unit has a function of generating cold air on one side and generating heat on the other side in accordance with the supply direction of the DC voltage and is provided between the bottom surface of the insulator and the upper surface of the insulator fixed body, (PTC) that is driven and generates cool air through the insulator to prevent overheating of the bus bar, and monitoring data on various components including temperature change data of the bus bar installed in the busbars, And a built-in server that outputs the data when the microcomputer requests the data.
The booth bar for the switchgear with the overheat prevention and remote monitoring function detects the temperature of the booth bar installed in the useful switchgear and, when the temperature of the booth bar rises above the predetermined temperature due to overload, between the bottom surface of the insulator and the upper surface of the insulator fixture And a built-in server that can store monitoring data of various components including temperature change data of the bus bar in the switchboard, And can be transmitted to a central monitoring room of a remote place or a personal computer carried by a manager.
However, when the high voltage current flows, the bus bar is overheated due to the exothermic phenomenon, and the electric conductivity is lowered due to the nature of the electric field drawn in the concentric circle, so that the voltage becomes unstable.
An embodiment of the present invention is to provide a busbar having a streamlined concavo-convex structure for circulating air by forming an air cooling passage through streamline machining on a busbar when current flows through the busbar.
Among the embodiments, the bus bar having a streamlined concavo-convex structure has a streamlined concave-convex structure for air cooling the metal plate-shaped busbars used to connect the two distribution boxes to move the current between the corresponding distribution boxes, The air is cooled through the streamlined irregularities formed on the upper surface of the drum.
In one embodiment, the air conditioner may further include a plurality of blowing fans for generating cooling wind to blow air to the streamlined irregularities to lower the temperature.
In one embodiment, the apparatus may further include a plurality of heat dissipating members inserted and fixed in the convex portions of the streamlined protrusions and protruding from the bus bar.
In one embodiment, the heat dissipating member may further include a connection heat dissipating member for connecting the heat dissipating member to radiate heat generated between the streamlined irregularities.
In one embodiment, the irregularities may include a plurality of grooves formed in the longitudinal direction on the upper surface of the streamlined irregularities about the streamlined irregularities.
In one embodiment, the irregularities may be formed in streamlined irregularities on the lower end surface of the bus bar so as to be offset from the streamlined irregularities formed on the upper surface of the bus bar.
The bus bar having a streamlined concavo-convex structure according to an embodiment of the present invention forms an air cooling passage through a streamlined process on the top surface of the bus bar to reduce the heat generated when a current flows in the bus bar, And the overheating of the bus bar can be prevented.
