Description
Technical field
The utility model relates to a kind of grounded screen analogue means, especially relates to a kind of grounded screen complex defect analogue means.
Background technology
Along with the development of national economy, more and more higher to the requirement of electric system reliability service, no matter be transmission line of electricity or transformer station, all need reliable and effective ground connection, the grounded screen of therefore electric system is the key equipment of electrical network.Because grounded screen is buried in underground, easily corrosion and breakpoint occur, cause stake resistance to become large, affect the reliability of ground connection, the detection therefore studying ground net corrosion and breakpoint is the key ensureing grounded screen safety.
Due to actual grounded screen once put into operation, be difficult to grasp its situation, therefore the research of grounded screen adopts the form of analogue ground net usually, arranges rational ground network defect to analogue ground net, and line correlation of going forward side by side research is the key ensureing Site Detection accuracy.
Utility model content
The purpose of this utility model is exactly to overcome the defect and the grounded screen complex defect analogue means that provides a kind of dirigibility good, easy to operate that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of grounded screen complex defect analogue means, it is characterized in that, comprise the analogue ground net and defects simulation unit that are made up of grounded screen body linkage section, described defects simulation cellular installation is in the optional position of analogue ground net, and described defects simulation unit comprises shell and the power-off defects simulation unit installed respectively in the enclosure and corrosion default analogue unit.
Snap fit is adopted to connect between the grounded screen body linkage section that described grounded screen body linkage section is adjacent.
Described power-off defects simulation unit and corrosion default analogue unit adopt and are arranged in parallel.
Snap fit is adopted to connect between the grounded screen body linkage section that described power-off defects simulation unit is adjacent.
Snap fit is adopted to connect between the grounded screen body linkage section that described corrosion default analogue unit is adjacent.
Described power-off defects simulation unit comprises two sections of metal wires, is provided with adjustable clearance between two sections of metal wires.
Described corrosion default analogue unit comprises artifical resistance.
Described shell is organic glass.
The described rectangular structure of analogue ground net.
Compared with prior art, analogue ground net is adopted connection segment mode by the utility model, the diverse location of the analogue unit access analogue ground net of grounded screen complex defect will be housed, the corrosion of analogue ground net diverse location and the simultaneous complex defect of breakpoint, the detect delay that can be grounded screen provides one effectively to test test product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model defects simulation unit.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
In order to meet the needs that electric system grounded screen fault detects, the utility model provides a kind of ground net corrosion and the simultaneous complex defect analogue means of breakpoint two kinds of defects, analogue ground net is adopted connection segment mode by this device, the diverse location of the analogue unit access analogue ground net of grounded screen complex defect will be housed, the corrosion of analogue ground net diverse location and the simultaneous complex defect of breakpoint, the detect delay that can be grounded screen provides one effectively to test test product.
As depicted in figs. 1 and 2, a kind of grounded screen complex defect analogue means, comprise the analogue ground net and defects simulation unit 3 that are made up of grounded screen body linkage section 1, described defects simulation unit 3 is arranged on the optional position of analogue ground net, and described defects simulation unit 3 comprises shell 6 and the power-off defects simulation unit 4 installed respectively in the enclosure and corrosion default analogue unit 5.
The present embodiment is the analogue ground net of 4 × 4, as shown in Figure 1.This grounded screen has 32 grounded screen body linkage sections 1, all adopts snap fit, arbitrarily can change linkage section between section and section.Tie point between 2 sections of being and section.As shown in Figure 2, wherein power-off defects simulation unit 4 adopts two sections of tinsel compositions to the concrete composition of defects simulation unit 3, there is certain distance between two sections of tinsels, the disconnection degree of the size simulation breakpoint of adjustable distance.Corrosion default analogue unit 5 adopts a resistance simulation ground net corrosion defect with certain resistance, by changing the different resistance of resistance adjustment, analogue ground net extent of corrosion.Breakpoint defect and corrosion default adopt form in parallel.Defective unit shell 6, adopts organic glass, to protect the resistance of corrosion simulation defect not by ectocine.Defective unit and grounded screen body linkage section adopt snap fit, can conveniently access grounded screen body.
Feature of the present utility model is, described defects simulation unit can be accessed by the optional position of analogue ground net, can the corrosion of analogue ground net diverse location and the simultaneous complex defect of breakpoint.
