Description

Switchgear unit with improved heat dissipation efficiency and blocking of foreign object inflow

The present invention relates to a switchgear unit provided to accommodate a transformer module, and more particularly, by having an improved heat dissipation structure and a structure to block the inflow of foreign substances including rainwater, The present invention relates to a switchgear unit having improved heat dissipation efficiency and a foreign substance inflow blocking rate capable of blocking the inflow of foreign substances that may be introduced from the outside while allowing heat and internal air to be more efficiently discharged to the outside.

A general switchboard unit distributes electricity to each load through a series of devices and prevents overcurrent from flowing. , is an aggregate of conductors (Busbar, Cable) that connect and connect the unit devices.

Such a switchboard unit is a device that constantly puts switches, instruments, relays (relays), etc. for the operation or control of power plants and substations, and the operation of electric motors. It is composed of an indoor switchboard unit that distributes and controls the power supplied from the outside to collective power demanders such as factories, factories, etc., through a bus-bar connected to the main circuit breaker and a plurality of auxiliary circuit breakers to protect human life and facilities. It supplies power to each indoor element and at the same time performs the function of opening/closing the supply power.

On the other hand, in operating the existing switchboard unit, excessive heat is generated inside the switchboard unit when the transformer module mounted on the switchboard unit is operated. Since the temperature of the switchboard unit suddenly rises or it is detected that the set temperature has been reached, the cooling fan is immediately operated to forcibly lower the internal temperature of the transformer module.

This cooling operation of cooling the temperature inside the enclosure of the switchboard unit through forced ventilation has a high heat dissipation efficiency, so the resistance temperature coefficient of various members and connection terminals and busbars in the transformer module increases, which can solve the problem of causing power loss. there was.

However, as in the prior art, when forced ventilation is performed through a cooling wind generated by simply driving a cooling fan, a dead zone, which is an area where the cooling wind cannot reach, is generated.

In particular, as the high-temperature hot air has the characteristic of staying above rather than below in a specific area, there is still a problem that thermal damage to the transformer module occurs due to the local increase in the temperature above the inside of the transformer. The need to develop a transformer module having a more stable heat dissipation structure is emerging.

On the other hand, in order to prevent the hot air from staying in the transformer, it was attempted to impart a heat dissipation effect by providing a plurality of heat sinks on the upper or lower plate of the transformer module. There is still a problem in that foreign substances or rainwater from the outside penetrate into the transformer, and damage to the transformer is concerned.

In addition, at least one second roof panel member 522 is disposed to be spaced apart from the first roof panel member 521 by a predetermined distance, and both ends are formed to extend upward, and It is provided so as to form an upper extension surface 522a spaced apart from the upper extension surface by a predetermined distance and disposed to face each other.

Next, the third roof panel member 523 extends upwardly between the upper extension surface 521b of the first roof panel member 521 and the second roof panel member 522 to prevent the inflow of foreign substances. It is provided to cover the space d3 between the surfaces 522a.

In this case, the bottom surface of the third roof panel member 523 is disposed to be spaced apart from the upper extension surfaces of the first roof panel member and the second roof panel member by a predetermined distance, and both ends of the third roof panel member 523 are bent downward, and are bent. An extension bent surface 523b may be formed in which one or more ends selected from among the formed ends are bent toward the spaced space between the upper extension surfaces.

In addition, the fourth roof panel member is provided to cover the space d4 between the upper extension surfaces of the second roof panel member, and has lower extension surfaces 524a having both ends bent downward on both sides. It may be formed to have a 'C'-shaped cross section, respectively.

In particular, the separation distance d3 between the upper extension surface 521b of the first roof panel member 521 and the upper extension surface 522a of the second roof panel member 522 is determined by a distance d3 between the second roof panel members. It is characterized in that it is formed to be equal to or smaller than the separation distance d4 between the upper extension surfaces 522a of the .

In addition, the width of the fourth roof panel member 524 is equal to or longer than the width of the third roof panel member 523 .

As described above, through the arrangement structure between the second roof panel members arranged to have an extended separation distance, a larger amount of heat can be discharged compared to other areas. By making it possible to expand the heat discharge from the zone side and the adjacent zone, more improved heat dissipation efficiency can be expected.

In addition, the above-mentioned upper extension surface 521b of the first roof panel member 521 , the upper extension surface 522a of the second roof panel member 522 , and the lower extension surface 523c of the third roof panel member 523 . ) and the downwardly extending surface 524a of the fourth roof panel member 524 may be provided so that a cross-section thereof has a shape inclined from the top to the bottom.

In more detail, the distal end of the upper extension surface 521b of the first roof panel member 521 may be bent toward the second roof panel member 522, and the second roof panel member 522 ), the end of the upwardly extending surface 522a may be bent in the direction of narrowing the separation distances d3 and d4.

In addition, the downwardly extending surface 523a of the third roof panel member 523 and the downwardly extending surface 524a of the fourth roof panel member 524 are the upwardly extending surfaces of the second roof panel member 522 . It may be provided to have a bending angle corresponding to 522a , and may be bent in a direction to narrow the separation distance between the third roof panel member 523 and the fourth roof panel member 524 .

Through the shape of the upper extension surface and the lower extension surface formed as described above, it is possible to improve the heat dissipation efficiency by improving the discharge rate of the heat generated by the transformation module.

In addition, when the upper extension surface and the lower extension surface have an inclined shape as described above, during the coating process to prevent corrosion of the roof panel members 521 , 522 , 523 , 524 , the upper extension surface and the Compared with the case where the downwardly extending surface has a vertically bent shape, as it allows the paint to penetrate the entire area of the panel member, it is possible to proceed with the painting more easily, resulting in improved corrosion resistance And it can provide the effect of being able to manufacture a switchboard unit with high quality.

Next, a switchboard unit according to another embodiment of the present invention will be described in more detail.
