Description
Technical field
The utility model belongs to field of power detection more particularly to a kind of Multifunctional electric cabinet discharging detecting system.
Background technology
In dielectric, due to manufacturing or some bubbles or other magazines can be remained in use, then exist
The electromagnetic field intensity that inside insulator or surface just will appear some regions is higher than average field intensity, and the electric field of some regions
Intensity is less than average field intensity, therefore will discharge first in some regions, and shelf depreciation in the insulator is even
Meeting etching insulative material, finally results in insulator breakdown, proves that shelf depreciation is that high voltage electric equipment is caused finally to send out according to statistics
The main reason for raw insulation breakdown, the apparatus function of monitoring shelf depreciation currently on the market is relatively simple, can not be in detection office
Portion can also detect the functions such as humiture, detection of electrical leakage, dehumidifying, earth leakage protective while electric discharge, cannot be satisfied the diversification of user
Demand.
Invention content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of can detection it is warm and humid
Degree, detection of electrical leakage, dehumidifying and the Multifunctional electric cabinet discharging detecting system with creepage protection function.
Technical solution used by the utility model is：The utility model includes babinet and is arranged in the micro- of box house
Processor unit, the microprocessor unit respectively with touch display screen, Partial Discharge Detection unit, detection of electrical leakage unit, leakage
Electric protection unit, Temperature Humidity Sensor and power supply unit electrical connection, the power supply unit and the heating unit and air-supply
Unit is electrically connected, and facility information virtual key, monitoring information virtual key and humiture letter are equipped in the touch display screen
Cease virtual key.
High Frequency Current Sensor and calibration impulse generator are provided in the Partial Discharge Detection unit.
The touch display screen is set to the front of the babinet, be additionally provided with below the touch display screen with it is described micro-
The USB interface of processor unit electrical connection, it is logical that the box back surface is additionally provided with 485 be electrically connected with the microprocessor unit
Communication interface, power interface, shelf depreciation input signal interface.
The shelf depreciation input signal interface further includes A interfaces, B interfaces, C interfaces and alarm signal output
Interface.
The blowing unit further includes Air Blast fan and scavenger fan.
The utility model has the beneficial effects that：Since the utility model includes babinet and is arranged at micro- place of box house
Manage device unit, the microprocessor unit respectively with touch display screen, Partial Discharge Detection unit, detection of electrical leakage unit, electric leakage
Protection location, Temperature Humidity Sensor and power supply unit electrical connection, the power supply unit and the heating unit and air-supply are single
Member electrical connection, the touch display screen is interior to be equipped with facility information virtual key, monitoring information virtual key and humiture information
Virtual key, compared with prior art the utility model increase residual current protective unit, detection of electrical leakage unit, heating unit and
Blowing unit, so detection of electrical leakage and earth leakage protective can also be carried out while detecting shelf depreciation and controlled in electrical cabinet
Humiture reduces the cost for installing multiple detection devices.
