Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] Based on the related technology, UHV substations are usually set up in the suburbs far away from the city center. If measurement is required, a large amount of manpower and material resources are required to extract voltage data from UHV substations. The process is relatively complicated. The embodiment of the present invention provides A VFTO remote measurement system, the structure of the system is shown as figure 1 shown, including:

[0027] The built-in probe sensor 10 is used to detect the ultra-fast transient overvoltage on the conductive rod in GIS / HGIS;

[0028] The acquisition card 20 is used to collect and record the voltage data detected by the built-in probe sensor;

[0029] The controller 30 is used to control the acquisition card to record the voltage data detected by the built-in probe sensor;

[0030] The tr...

Abstract

The invention discloses a very fast transient overvoltage (VFTO) remote measurement system and a method. The system comprises a built-in probe sensor which is used for detecting VFTO on a conducting rod in a gas insulated switchgear or a hybrid gas insulated switchgear (GIS / HGIS), an acquisition card which is used for acquiring and recording voltage data detected by the built-in probe sensor, a controller which is used for controlling the acquisition card so that the acquisition card records the voltage data detected by the built-in probe sensor, a transmission device which is used for uploading the voltage data recorded by the acquisition card to the network to achieve remote measurement, and a storage battery which is used for providing electric energy for an inner circuit of the VFTO remote measurement system. The VFTO remote measurement system and the method solve the problem that the process of measurement of an overvoltage transformer substation is complicated due to the fact that acquisition of voltage data requires a large quantity of manpower and material resources as the overvoltage transformer substation is usually built in the suburbs which are far away from the downtown, operators do not need to go to the overvoltage transformer substation anymore for the acquisition of the voltage data, the manpower and the material resources are saved, and convenience of operation is improved.

Description

technical field [0001] The present invention relates to the fields of electrical control and electrical measurement, and more specifically, to a very fast transient overvoltage (Very Fast Transient Overvohage, referred to as VFTO) remote measurement system and method. Background technique [0002] Actual operating experience shows that when the disconnector, grounding switch and circuit breaker in the gas insulated switchgear (GIS for short) / hybrid gas insulated switchgear (HGIS for short) are operated, there will be VFTO with high amplitude, large steepness and high frequency. GIS / HGIS is commonly used in UHV projects, and the existence of VFTO poses a serious threat to the safe operation and operation of electrical equipment. Therefore, it is especially important to measure VFTO accurately. [0003] Due to the consideration of the external complex electromagnetic environment in the existing measurement system for VFTO, the measurement equipment needs to be placed in a sh...
