Description

[0001] APPARATUS FOR CONTROLLING FIRE OF SWITCHGEAR [0002]

FIELD OF THE INVENTION The present invention relates to a fire control apparatus for a switchboard, and more particularly, to a fire control apparatus for a switchboard that can detect and extinguish a fire in a switchboard in real time.

Generally, it is impossible to supply electric power which can be used as it is from the electric power company like general electric equipment of low voltage of 110V or 220V because electric power of private use such as building or factory is large.

Therefore, in the case of general household electrical equipment, a high voltage of 3,300 V or 6,600 V is to be received from the distribution line of the substation and then transformed to a commercial voltage again.

Particularly, in a large-sized building, a high voltage of 22.9 kV is required to be supplied to a commercial power supply, and the transformer must be transformed into a commercial voltage.

These switchboards include a distribution panel, a motor control center panel, a low-pressure panel, a high-pressure panel, a transformer panel, and an extra-high pressure panel.

These switchgear substations are equipped with power receiving facilities for receiving high voltage and special high voltage supplied from substations, substation facilities for substracting high voltage and special high voltage received from substations to commercial voltage, It is formed as a distribution facility for supplying electricity to supply the electricity safely and efficiently into the building.

Domestic authorized voltage such as 22.9KV, 6.6KV, 3.3KV, 440V, 380 / 220V such as transformer, circuit breaker, and condenser is always applied to the inside of such a switchboard.

The temperature is increased by 10 ~ 30 degrees compared to the ambient temperature, such as heat loss due to no-load loss or load loss, heat generated by the soot during operation of the circuit breaker, heat generated by charge accumulation such as a condenser,

That is, the greatest risk of accident in such a switchboard is the temperature rise due to the heat generated from the electric power equipment which processes the voltage conversion, and the fire risk due to the spark caused by the electric power device.

Such a fire in the switchboard may cause a power interruption due to the stoppage of the switchboard, and the internal temperature control of the switchboard and the fire detection technology are very important because a building equipped with a switchboard has a fire risk.

As a conventional technique for detecting such a fire, a " remote temperature / fire detection system and its method " in Korean Registered Patent No. 0998531 is known.

This technology is equipped with various sensors to detect the temperature and fire inside the switchboard, and it is a system and method which can remotely control by using information through the sensors.

However, since this technology is fixed at a designated position, there is a problem that a fire can not be detected when a fire occurs outside the sensing range of the sensor.

When the sensor senses a fire, the fire is already in a largely fluctuated state, so that it can not be reversed.

Patent No. 10-0998531
