Abstract
The utility model relates to a kind of grounded screen breakpoint defects simulation device, comprise the analogue ground net and breakpoint defects simulation unit that are made up of multiple grounded screen body linkage section, this breakpoint defects simulation unit is connected on the optional position of analogue ground net, and described breakpoint defects simulation unit comprises breakpoint defective unit and the shell for installing breakpoint defective unit.Compared with prior art, the utility model has the advantages such as dirigibility is good, easy to operate.
Description
Technical field
The utility model relates to a kind of grounded screen analogue means, especially relates to a kind of grounded screen breakpoint defects simulation device.
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 corrode, produce breakpoint, affect the reliability of ground connection, the detection therefore studying grounded screen 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 breakpoint defects simulation device 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 breakpoint defects simulation device, it is characterized in that, comprise the analogue ground net and breakpoint defects simulation unit that are made up of multiple grounded screen body linkage section, this breakpoint defects simulation unit is connected on the optional position of analogue ground net, and described breakpoint defects simulation unit comprises breakpoint defective unit and the shell for installing breakpoint defective unit.
Snap fit is adopted to be connected between described grounded screen body linkage section with adjacent earth mat body linkage section.
The grounded screen body linkage section that described breakpoint defective unit is adjacent adopts snap fit to connect.
Described breakpoint defective unit comprises two sections of metal wires, is provided with adjustable clearance between these two sections of metal wires.
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 breakpoint defect will be housed, the breakpoint defect of analogue ground net diverse location, 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 breakpoint 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 grounded screen breakpoint defects simulation device, 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 breakpoint defect will be housed, the breakpoint defect of analogue ground net diverse location, 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 breakpoint defects simulation device, comprise the analogue ground net and breakpoint defects simulation unit 3 that are made up of multiple grounded screen body linkage section 1, this breakpoint defects simulation unit 3 is connected on the optional position of analogue ground net, and described breakpoint defects simulation unit 3 comprises breakpoint defective unit 4 and the shell 5 for installing breakpoint defective unit.
The present embodiment is the analogue ground net of 4 × 4, as shown in Figure 1.Have 32 grounded screen body linkage sections 1, all adopt snap fit between section and section, arbitrarily can change linkage section.Tie point between 2 sections of being and section.As shown in Figure 2, its point of interruption defective unit 4 is two sections of metal wire compositions to the concrete composition of breakpoint defects simulation unit 3, and be separated with certain distance between two sections of metal wires, analogue ground net breakpoint, the distance between two sections can regulate arbitrarily, simulation breakpoint breaking degree.Breakpoint defective unit shell 5, adopts organic glass, to protect breakpoint defect not by ectocine.Breakpoint 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 breakpoint analogue unit can be accessed by the optional position of analogue ground net, can the breakpoint defect of analogue ground net diverse location.
