In general, the power and distribution system is a power supply system that converts power from special high voltage to low voltage and supplies electric power to apartments, buildings, schools, factories, ports, etc. Generally, it has capacity of 80-700 kW.

Most of the switchgear equipments include a transformer, an optimum operation controller of the transformer, a power monitoring controller, etc., and a single-enclosure high-low-pressure one-piece type having a multi-layered structure for preventing external moisture and foreign matter from entering, .

In particular, the power monitoring controller installed inside the high and low pressure integrated switchboard processes the sensed values of the temperature sensor and the current voltage sensor to extract information such as the operating temperature, load factor, phase loss factor, power factor, harmonic factor, and imbalance ratio of the high voltage transformer It is also notified to the administrator through the LCD display attached to the power monitoring controller and also transmitted to the remote management system through the communication interface device.

The conventional power transmission and distribution panel includes an enclosure case for housing various electric devices, a pair of doors provided with a sight window for inspecting the enclosure case, various electric devices housed in the enclosure case, and an air inlet .

The air inlet portion is formed so that external cold air is drawn into the enclosure case and a blowing fan is installed at an upper portion of the enclosure case to exhaust heat discharged from various electric appliances accommodated in the enclosure case .

That is, the cold air introduced into the air inflow portion is discharged to the outside through the inside of the enclosure case through the air blowing fan, so that the cold air drawn from the outside is supplied into the enclosure case to effectively cool various electric devices in the enclosure case .

However, in the above-described conventional switchgear, the external cold air flowing through the air inlet moves along a single air circulating flow path, and air trapping occurs in a part of the enclosure case.

Therefore, an air collecting device is needed which cleans the power plant due to the inflow of external dust contained in the air by the external air sucking. For this purpose, a conventional axial flow fan is installed to ventilate a part of the transmission and distribution system to prevent the flow of turbulence, and a dust filter is installed in the atmospheric air inlet from the outside and the air outlet from the outside to reduce external dust inflow Respectively.

However, as mentioned above, the switchgear has a vicious circle in which the dust accumulates in the inner space and becomes sticky when it is wet, so that the epoxy part is changed into the insulator or the whole peninsula and deterioration due to the insulation breakdown and the fine flares are enlarged, Which was caused by an electric accident.

In order to solve the above-mentioned problem, the present invention measures a concentration and a thickness of an internal dust, and when the measured value is equal to or more than a reference value, it delivers the alarm to the manager so as to prevent an electric accident through internal cleaning, The purpose is to provide.

According to an aspect of the present invention, there is provided a switchgear comprising: an enclosure case having an inner space and forming an outer appearance; a pair of doors provided in front of the enclosure case; And a power supply device for converting high-voltage power into low-voltage for supplying power to the external case, wherein the cleaning state determination unit is installed in an inner space of the case case to measure and analyze the concentration and thickness of the dust, .

Here, the cleaning determination unit may include an air concentration measuring unit for measuring a concentration of dust contained in the air existing in the case case, a dust thickness measuring unit for measuring a thickness of the dust accumulated in the case case, An analyzing unit that receives the measured dust concentration and thickness from the dust concentration measuring unit and the dust thickness measuring unit and compares and analyzes the measured value with the reference value; and a communication unit that transmits the analyzed result through the analyzing unit to the outside.

The freshness determination unit may further include an optical sensor for detecting an arc in the enclosure case and an electromagnetic wave sensor for detecting a partial discharge.

The switchboard according to the present invention has the following effects.

That is, when the thickness of the inside of the switchgear is measured including the concentration of dust and the measured value is over the reference value, it is delivered to the manager so that the MOF and the electric motor can be prevented from being burned out through internal cleaning.
