Abstract

The utility model discloses a sensor device for detecting high-voltage current and voltage on line. The device includes a high-voltage lead, a voltage transformer, a current transformer, and a sensor housing. The sensor device for detecting high-voltage current and voltage on line has the advantages of safe and reliable measurement manner and simple structure.

Description

The sensor device of a kind of online detection high-tension current and voltage
Technical field
The utility model belongs to the automatic measure control field, relates in particular to a kind of online detection high-tension current in online detection and the sensor device of voltage.
Background technology
Along with the development of power electronic devices, be accompanied by a large amount of power electronic equipment ranges of application more and more extensive, the important parameter of weighing power electronic equipment insulating property quality is the size of its insulating resistance value.The online quality that detects the insulativity of a large amount of power electronic equipments can not adopt surveying instrument commonly used, as digital multimeter, megohmmeter, insulation multimeter, Hi-pot Tester etc.
Reason is to adopt means commonly used to have very large drawbacks when measuring: during measurement operation very inconvenient, measuring accuracy is very low, mainly is used in non-on-line measurement.Megohmmeter commonly used is exactly a kind of insulation measurement instrument commonly used, and it is to weigh the high resistance megohmmeter of insulation degradation situation by measuring resistance under condition of high voltage.The susceptibility withstand voltage due to power electronic devices is very strong, under high-pressure situations, is easy to cause device to damage because of high pressure.Therefore for the problem of above existence, on original detection basis, carry out new revising of the functions, the sensor device of innovation electric current and voltage, make it to carry out online the insulation resistance detection, has that metering system is safe and reliable, advantages of simple structure and simple.
Summary of the invention
The purpose of this utility model is to provide the sensor device of a kind of online detection high-tension current and voltage, for online, detects the High-Voltage Insulation impedance, has that metering system is safe and reliable, advantages of simple structure and simple.
The technical scheme that realizes above-mentioned purpose is: the sensor device of a kind of online detection high-tension current and voltage comprises: high-voltage conducting wires, voltage transformer (VT), current transformer and sensor outer housing; Wherein:
Described high-voltage conducting wires passes from described current transformer and described sensor outer housing center, and described voltage transformer (VT) is positioned at the upper left side of described sensor outer housing, and described current transformer is positioned at the below of described sensor outer housing, with described sensor outer housing, keeps concentric.
Above-mentioned voltage transformer (VT) is by two keeping parallelisms and keep the sheet metal of fixed range to form with above-mentioned high-voltage conducting wires each other.
Above-mentioned sensor outer housing is the deblocking metal shell, and is connected with the nonmetallic insulation of employing between above-mentioned voltage transformer (VT) and above-mentioned current transformer.
Owing to having adopted the utility model device, the sensor device of a kind of online detection high-tension current and voltage is provided, detect the High-Voltage Insulation impedance for online, have that metering system is safe and reliable, advantages of simple structure and simple.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Please refer to Fig. 1, provided the sensor device of a kind of online detection high-tension current and voltage in figure, comprising: high-voltage conducting wires 1, voltage transformer (VT) 2, current transformer 3 and sensor outer housing 4; Wherein:
High-voltage conducting wires 1 passes from current transformer 3 and sensor outer housing 4 centers, and voltage transformer (VT) 2 is positioned at the upper left side of sensor outer housing 4, and current transformer 3 is positioned at the below of sensor outer housing 4, with sensor outer housing 4, keeps concentric.
Voltage transformer (VT) 2 is by two keeping parallelisms and keep the sheet metal of fixed range to form with high-voltage conducting wires 1 each other.
Sensor outer housing 4 is the deblocking metal shell, and is connected with the nonmetallic insulation of employing between voltage transformer (VT) 2 summation current transformers 3.
Principle of work of the present utility model is the inductive action of utilizing in ac high-voltage electric field and magnetic field, realizes the sensor device of a kind of online detection high-tension current and voltage, has that metering system is safe and reliable, advantages of simple structure and simple.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model will be usingd scope that appended claims defines as protection domain of the present utility model.
