Embodiment 1

[0031] Such as figure 1 As shown, a passive electronic voltage sensor provided by an embodiment of the present invention includes a film capacitor 01 and a potting body, and the potting body includes an inner potting body 02 and an outer potting body 03 . The film capacitor 01 is arranged inside the inner casting body 02 , and the outer casting body 03 is arranged outside the inner casting body 03 .

[0032] The passive electronic voltage sensor provided by the embodiment of the present invention encapsulates the film capacitor through a layered casting body, which can solve the problems of existing sensors such as air bubbles, cracks and partial discharge, and can ensure the electrical insulation performance of the passive electronic sensor.

[0033] Such as figure 2 As shown, the film capacitor 01 includes a first electrode layer 13 and a second electrode layer 16, and an insulating layer 17 is filled between the first electrode layer 13 and the second electrode layer 16, ...

Embodiment 2

[0041] An embodiment of the present invention provides a method for manufacturing a passive electronic voltage sensor, which can be used to manufacture the passive electronic voltage sensor 01 as described in Embodiment 1, such as image 3 As shown, the method includes the following steps:

[0042] Step 1: select the metallized polypropylene film as the base material, cut out the first base film 11, the second base film 14 and the dielectric film 18 according to the required size, and plate the first metal layer 12 on the first base film 11 to form The first electrode layer 13 is plated with the second metal layer 15 on the second base film 14 to form the second electrode layer 16. The structures of the first metal layer 12 and the second metal layer 15 can be referred to figure 2 ;

[0043] Wherein, the metallized polypropylene film can be prepared by metallizing the polypropylene film.

[0044] Step 2: the pre-cut polypropylene film is placed between the first electrode l...

Abstract

The invention discloses a passive electronic voltage sensor and a manufacturing method thereof. The sensor comprises a casting body and a thin-film capacitor arranged in the casting body; the thin-film capacitor comprises a first electrode layer, a second electrode layer opposite to the first electrode layer, and an insulating layer filled between the first electrode layer and the second electrodelayer; the first electrode layer comprises a first base film and at least two first metal layers arranged on the first base film, and a gap is reserved between every two adjacent first metal layers;the second electrode layer comprises a second base film and a second metal layer arranged on the second base film, wherein the second metal layer and the first metal layers can form capacitors respectively, and the capacitors can be connected in series. The passive electronic voltage sensor is small in size and convenient to install, and the partial discharge performance of the voltage sensor is improved through an epoxy pouring process.

Description

technical field [0001] The invention relates to the technical field of voltage sensors, in particular to a passive electronic voltage sensor and a manufacturing method thereof. Background technique [0002] At present, the State Grid Corporation of China is carrying out the construction of smart grid in an all-round way, and is transforming the urban and rural power grids. The primary and secondary integration of power distribution is an important means and measure to improve the reliability, technological advancement and professional operation and maintenance of power distribution equipment, and it is also an important basis for realizing smart distribution network. Since the primary and secondary fusion work of power distribution was carried out, AC sensors have played a key role in the monitoring of power grid operation. [0003] Passive electronic voltage sensors can convert the high-voltage side electrical signals in the distribution network into small voltage signal o...
