Storage diagnostic test function solves the problems, such as construction and electric energy meter PORT COM；And use self diagnosis wiring faults collector
After avoid using Wiring diagnosis device, so as to reduce the purchase of Wiring diagnosis device, meanwhile, reduce artificial setting up time,
Wiring efficiency is improved, is also avoided because wiring faults need manually to go to the expense at scene；And self diagnosis wiring faults
The use of collector not only shortens setting up time, but also effectively controls the security risk at scene.Since equipment volume is small,
It can be mounted in ammeter box, ensure equipment safety；And self diagnosis wiring faults collector greatly improves power information and adopts
The success rate of collection has effectively ensured meter reading success rate, it is ensured that user can receive bill in the defined time.
In a preferred but unrestricted embodiment of the invention, shell is further included, the shell is by makrolon and propylene
Nitrile-butadiene-styrene copolymer is formed.PC+ABS plastic polycarbonates and acrylonitrile-butadiene-styrol copolymer and
Mixture is the thermoplastic plastic rubber formed by makrolon (Polycarbo nate) and smart (ABS) alloy of polypropylene, with reference to
The excellent specific properties of two kinds of materials.Advantage：Performance synthesis is preferable, and impact strength is higher, chemical stability, and electrical property is good；It is resistance to
Hot raising, hardness improve.
Temperature -200--260 degree is used for a long time in Ptfe plastics, has remarkable chemical resistance, to all chemicals all
Corrosion-resistant, friction coefficient is minimum in the plastic, and also good electrical property, electrical insulating property is not affected by temperature, and has " plastics
The title of king ".Advantage：Ptfe has an outstanding excellent comprehensive performance, ptfe high temperature resistants, and ptfe is corrosion-resistant, not viscous, self-lubricating, excellent
Good dielectric properties, very low friction coefficient.Shortcoming：In contrast expensive, mobile performance is poor.
The shell of the present invention can be reached using makrolon and acrylonitrile-butadiene-styrene copolymer and mixture
Comprehensive performance is preferable, and impact strength is higher, chemical stability, and electrical property is good；Heat resistance improves, and hardness improves.
The specific Application Example of the present invention presented below, of the invention is connect using self diagnosis wiring faults collector
Line is compared with conventional connections, and data are as shown in table 1
With reference to shown in table 1, the wiring success rate of self diagnosis wiring faults collector is demonstrated higher than conventional connections, works as discovery
During wiring faults, collector can reliably reflect in time, the realization of goal of project design.
In this application embodiment, using being avoided after self diagnosis wiring faults collector using Wiring diagnosis device, from
And reduce the purchase of Wiring diagnosis device, meanwhile, reduce artificial setting up time, improve wiring efficiency, also avoid because
Wiring faults need manually to go to the expense at scene.
By taking in November, 2015 as an example, 4 wiring faults occur altogether, then the expense for finding to generate after wiring faults is：It is oily to take：
6*30*4=720 members.And so on, the economic benefit of 1 year is about 8640 yuan.
In conclusion the use of self diagnosis wiring faults collector, not only shortens setting up time, but also effectively control
The security risk at scene.It since equipment volume is small, can be mounted in ammeter box, ensure equipment safety and self diagnosis wiring event
Barrier collector greatly improves the success rate of power information acquisition, has effectively ensured meter reading success rate, it is ensured that user can be
The defined time receives bill.
