Description
Technical field
The utility model relates to the High-Voltage Electrical Appliances field, relates in particular to a kind of novel voltage sensor of measuring voltage in the power industry.
Background technology
Voltage sensor is a kind of sensing element that high pressure more than the 10kV is converted to 220V and following voltage.Traditional voltage sensor is generally realized by the mutual inductor of electromagnetic type.But along with the raising of electric pressure, size and the weight of electromagnetic transformer all increase, and are unfavorable for the simplification of integral miniaturization and manufacturing process; And the measurement result of mutual inductor is because the restriction of magnetic characteristic unshakable in one's determination can not be satisfied the demand for development of the high reliability of electric system proposition.And electronic mutual inductor can remedy these deficiencies of electromagnetic transformer preferably, therefore has preferably development prospect.Simultaneously, along with application demand need not, people also more and more are tending towards different to high pressure to the ratio of low pressure conversion.
The utility model content
For the shortcoming of existing voltage sensor, the utility model provides a kind of novel voltage sensor, have simple in structure, volume is little, the advantage such as easy for installation, can according to actual needs, realize that different high pressure arrives the conversion ratio of low pressure simultaneously.To achieve these goals, technical solution adopted in the utility model is, a kind of novel voltage sensor, comprise insulator foot, ground connection shell, intercalation cylinder, bus, screw, wherein, ground connection shell, intercalation cylinder, bus are fixed on the insulator foot, and the ground connection shell is at outermost layer, bus is positioned at middle, and the intercalation cylinder is between ground connection shell and bus; Between ground connection shell and the intercalation cylinder, be filled with insulating material between intercalation cylinder and the bus; Screw is connected between ground connection shell and the intercalation cylinder; Ground connection shell, intercalation cylinder, bus are conductive material; Screw is insulating material; The intercalation cylinder is connected with two electrodes of output voltage respectively with the ground connection shell.
A kind of novel voltage sensor that the utility model provides, between ground connection shell and bus, insert one deck intercalation cylinder, formed the series connection of two electric capacity between ground connection shell and intercalation cylinder, intercalation cylinder and the bus, by the principle of series connection dividing potential drop, realized that high pressure is to the conversion of low pressure.Before filling megohmite insulant, can be fixed by screws in different height to the intercalation cylinder, realize that different high pressure is to the conversion ratio of low pressure.The utlity model has simple in structure, volume is little, easy for installation, accuracy is high, can change high pressure the advantage such as compares to low pressure conversion.
