Abstract
The invention discloses a tester for a zinc oxide arrester, comprising a voltage regulation device, a boosting device, a voltage measuring device and a current measuring device, wherein the voltage regulation device has zero position protection; when a voltage regulator is not on the zero position, the device can not boost; the boosting device comprises two test transformers adopting serial wiring; the voltage measuring device is provided with a standard voltage divider at a high-voltage side; the current measuring device can measure the total current, the resistive current and the capacitance current of the zinc oxide arrester; the device is integrated; and the test transformer has small volume and is in series excitation, which reduces the weight of the test transformer and is convenient to carry. After the tester for the zinc oxide arrester is used, no resistive current tester is required. The device combines voltage regulation and measurement into a whole and has the advantages of small volume and light weight, is simple in operation and convenient in measurement, and is convenient for test sites.

Technical field
The present invention relates to the proving installation of a kind of proving installation, particularly a kind of Zinc-Oxide Arrester, belong to electrical technology field.
Background technology
According to the regulation of standard GB 50150---2006 " electrical equipment commissioning test standard ", should measure AC power frequency reference voltage and persistent current to Zinc-Oxide Arrester.Traditional test method is to use, pressure regulator, testing transformer, capacitive divider, testing current in resistance property instrument etc.The instrument and equipment that needs is more, the testing equipment heaviness, and the testing ground carrying is inconvenient.
Zinc-Oxide Arrester proving installation newly developed is considered above problem, and this device adopts aggregation type.Testing transformer adopts low capacity, series excitation type, has reduced the weight of testing transformer, and is easy to carry.After using the Zinc-Oxide Arrester proving installation, just can be without the testing current in resistance property instrument.
This device is with pressure regulation and be measured as one, and is simple to operate, and it is convenient to measure.Volume is little, and is in light weight, is convenient to the testing ground and uses.
Summary of the invention
At the technical matters of above-mentioned existence, the purpose of this invention is to provide a kind of long-pending for a short time, in light weight, be convenient to the proving installation of the Zinc-Oxide Arrester that uses the testing ground.
Realize that technical scheme of the present invention is: a kind of proving installation of Zinc-Oxide Arrester comprises regulator, increasing apparatus, voltage measuring apparatus, current measuring device; Described regulator has zero position protection, and when pressure regulator during not in zero-bit, this device can not boost; Described increasing apparatus comprises two bench teats and tests transformer, adopts the wiring of tandem formula; Described voltage measuring apparatus has standard voltage divider in the high-pressure side.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
This device adopts aggregation type.Testing transformer adopts low capacity, series excitation type, has reduced the weight of testing transformer, and is easy to carry.After using Zinc-Oxide Arrester to exchange integrated test set, just can be without the testing current in resistance property instrument; This device is with pressure regulation and be measured as one, and is simple to operate, and it is convenient to measure.Volume is little, and is in light weight, is convenient to the testing ground and uses.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of the proving installation of Zinc-Oxide Arrester of the present invention.
Embodiment:
The proving installation of a kind of Zinc-Oxide Arrester of the present invention as shown in Figure 1 comprises regulator, increasing apparatus, voltage measuring apparatus, current measuring device; Described regulator has zero position protection, and when pressure regulator during not in zero-bit, this device can not boost; Described increasing apparatus comprises two bench teats and tests transformer, adopts the wiring of tandem formula; Described voltage measuring apparatus has standard voltage divider in the high-pressure side; Described current measuring device can be measured total current, current in resistance property, the capacitance current of Zinc-Oxide Arrester.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
This device adopts aggregation type.Testing transformer adopts low capacity, series excitation type, has reduced the weight of testing transformer, and is easy to carry.After using the Zinc-Oxide Arrester proving installation, just can be without the testing current in resistance property instrument; This device is with pressure regulation and be measured as one, and is simple to operate, and it is convenient to measure.Volume is little, and is in light weight, is convenient to the testing ground and uses.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the present invention, all drop within the rights protection scope of the present invention.
