Abstract
The utility model relates to an anti-electromagnetic interference electric power detection system cabinet, belongs to the technical field of the power equipment. The anti-electromagnetic interference electric power detection system cabinet mainly comprises a casing body, an amplifier, a power supply adapter, an industrial control computer, an air conditioner and a power supply. An insolating transformer is installed between the amplifier, the industrial control computer and the power supply. A front end magnetic ring is rolled on the power line on the entrance of the amplifier. A back end magnetic ring is rolled on the power line on the entrance of the industrial control computer. The insolating transformer, the front end magnetic ring and the back end magnetic ring can filter the transient interference on the power supply side and the ground wire accessing, which can provide a safe and reliable working environment for the amplifier and the industrial control computer. The utility model can effectively prevent the electromagnetic interference. The precision of the detecting system is greatly improved, and furthermore, the operation of the power transmission system is safer.
Description
Technical field:
The utility model belongs to the electric supply installation technical field, is a kind of industrial computer and electronic equipment such as amplifier rack that normal operation circumstances is provided for the electric power detection system.
Background technology:
It mainly is for normal operation circumstances being provided for electronic equipments such as industrial computer and amplifier, to adapt to the different regions climate difference, as temperature, humidity etc. that electric power is carried the on-the-spot industrial temperature control rack of electric substation.Rack mainly comprises shell body, amplifier, power supply adaptor, industrial computer, air conditioner and power supply, the high-frequency discharge signal that amplifier receiving sensor probe is gathered amplifies, give industrial computer through power supply adaptor and carry out signal Processing, power supply is respectively to power devices such as air conditioner, amplifier and industrial computers.Because from the electromagnetic interference (EMI) of power supply, ground wire etc., the degree of accuracy of detection system is affected.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of anti-electromagnetic interference (EMI) electric power detection system rack.
The scheme of the utility model technical solution problem is between amplifier and industrial computer and power supply isolating transformer to be housed, and is wound with the front end magnet ring on the power lead of amplifier porch, is wound with the rear end magnet ring on the power lead of industrial computer porch.Isolating transformer, front end magnet ring and rear end magnet ring can filter the glitch that mains side and ground wire are scurried into, and make amplifier and industrial computer that a safe and reliable working environment be arranged.
Between power supply adaptor and isolating transformer, power-supply filter is housed, enters in the power supply adaptor by power lead with the electromagnetic exposure that prevents to produce in the industrial computer.
Between power-supply filter and isolating transformer, ups power is housed, with the mishap that prevents to cut off the power supply and cause.
The utility model can prevent electromagnetic interference (EMI) effectively, and antijamming capability is strong in the rack, and the degree of accuracy of detection system is greatly improved, thereby makes the electrical power transmission system operation safer, simple in structure, reliable working performance.
