Abstract
A mechanical structure for a zinc oxide testing instrument is disclosed. The mechanical structure for a zinc oxide testing instrument comprises a zinc oxide testing instrument outer shell and a plurality of high-voltage wire connecting electrodes arranged on the outer shell. The mechanical structure for a zinc oxide testing instrument is characterized in that a built-in electrode umbrella skirt insulation structure is adopted for each of the plurality of high-voltage wire connecting electrodes, and the built-in electrode umbrella skirt insulation structure is characterized in that an umbrella skirt-structured insulator of which the upper part and the lower part are communicated with each other is wrapped around each high-voltage wire connecting electrode. The built-in electrode umbrella skirt insulation structure is adopted in the zinc oxide testing instrument, and therefore creepage distance is guaranteed while an interval between every two wire connecting electrodes is decreased, the zinc oxide testing instrument is enabled to be greatly reduced in size, and safety and convenience are realized when the zinc oxide testing instrument is used by a user.
Description
Technical field
The utility model relates to a kind of over-voltage protection technique field, is specifically related to a kind of proving installation of overvoltage protection resistor.
Background technology
Fast development along with national economy; electric system is in producing and living, and particularly industrial and mining enterprises occupy very important status in producing, and the stable operation that guarantees thus electric system is the prerequisite guaranteed safe production; therefore, various electrical protection apparatus are applied more and more in electric system.Zinc paste overvoltage protection equipment is a kind of as electrical protection apparatus, damages because of overvoltage in order to prevent power equipment, when practical application, often needs it is done to a large amount of tests and test.Current existing zinc paste tester is provided with many high-voltage connection terminals because of it, for ensureing the security of test and test, between high-voltage connection terminal, needs to leave safe spacing, therefore causes small product size excessive, transports, carries and all inconvenient while using.
Summary of the invention
According to the problem that prior art exists, the utility model provides a kind of physical construction of zinc paste tester, and this structure has greatly reduced the safe spacing between each high-voltage connection terminal, has reduced the volume of tester, greatly facilitates the user and uses.
The utility model realizes that the technical scheme of above-mentioned purpose is as follows:
A kind of physical construction of zinc paste tester, comprise a zinc paste tester shell, be arranged at a plurality of high-voltage connection electrodes on shell, it is characterized in that described a plurality of high-voltage connection electrode adopts the built-in full skirt insulation system of electrode;
The built-in full skirt insulation system of described electrode is the insulation at outer wrap penetrating umbrella skirt construction Shang Xia of each high-voltage connection electrode.
For the zinc paste tester used in general three-phase electrical power system, its shell is provided with 3 high-voltage connection electrodes, and each electrode outer wrap has the insulator of umbrella skirt construction penetrating Shang Xia.
The utility model has following outstanding advantage and effect compared to prior art: the physical construction of the zinc paste tester provided due to the utility model has adopted the built-in full skirt insulation system of electrode, therefore when guaranteeing creepage distance, reduced the spacing of each link electrode, make the volume of zinc paste tester greatly reduce, the user is safer, convenient in use.
The accompanying drawing explanation
Fig. 1 is the cross-sectional view of a specific embodiment of physical construction of a kind of zinc paste tester described in the utility model.
Embodiment
Referring to Fig. 1, the present embodiment is the physical construction for the zinc paste tester of three-phase 10kV electric system, this structure comprises that a zinc paste tester shell 3, three are be used to connecting three-phase high-voltage bus A, B, the three-phase high-voltage link electrode 2 of C, it is characterized in that described a plurality of high-voltage connection electrode 2 adopts the built-in full skirt insulation system of electrode, described built-in full skirt insulation system is the insulator 1 at outer wrap penetrating umbrella skirt construction Shang Xia of each high-voltage connection electrode 2.
Because the zinc paste tester has adopted the built-in full skirt insulation system of electrode, therefore when guaranteeing creepage distance, reduced the spacing of each link electrode, it is very little that the volume of this zinc paste tester can be done, and greatly facilitates use.During use, will with three three-phase high-voltage link electrodes 2 of zinc paste tester, be connected respectively with the connection terminal of three-phase alternating current high pressure, can open tester after after wiring completes and start test.
