Description
Technical field
The present invention relates to a kind of platform sheet relation detection method, be applicable in electric system, identify subscriber board sheet and phase sequence attribute, be beneficial to and realize the fine-grained management of platform sheet relation.
Background technology
Vigorously implement at present the macroeconomic situation of collectivized operation, intensivization development and lean management in State Grid Corporation of China under, the fine-grained management of platform sheet has become one of important process of grid company at different levels.But due to historical reasons, the materials such as early stage platform sheet user profile, measuring apparatus data, underground cable and service conductor path profile, business sheet are incomplete, add upper part low-voltage customer and privately overlap supply line, make adjacent stations sheet cross link intricate, be difficult to transformer and phase sequence thereof belonging to determining table sheet user, the examination of platform sheet line loss is directly caused to implement completely, the metering caused thus, credits dispute are of common occurrence, directly increase the business risk of power supply enterprise, make Business Economic Benefit be subject to heavy losses.In this case, management of power use department needs to use platform sheet relation test instrument to investigate thoroughly platform sheet and the phase sequence attribute of user, grasps basic data really and accurately.
According to the knowledge of the applicant, in the actual testing process of platform sheet relation test instrument, carrier signal can be transferred to high-pressure side by transformer, then is transferred to adjacent transformers by hi-line, causes " getting lines crossed " phenomenon i.e. " high pressure is being got lines crossed altogether ".Same reason, if adjacent transformers has common ground situation, carrier signal also can got lines crossed to adjacent transformers, namely " gets lines crossed altogether "; If the low-voltage cable of adjacent transformers walks same cable ditch, carrier signal can got lines crossed by the coupling capacitance between cable adjacent transformers, i.e. " cable duct is being got lines crossed altogether ".
The failure of platform sheet relation test is caused for avoiding " getting lines crossed " phenomenon, currently available technology has started the two-way confirmation formula platform sheet recognition methods (such as the Chinese utility model patent of application number 200820234129.9 Authorization Notice No. CN201352239Y) adopting pulsed current signal and power carrier signal to combine, detailed process is: first send pulsed current signal by hand-held receiving terminal, again by there is the Host Detection of pulse current detection circuit after current pulse signal, then power carrier signal is sent by main frame, finally detect this power carrier signal by hand-held receiving terminal, thus final platform sheet and the phase sequence attribute confirming active user, avoid being subject to " getting lines crossed " phenomena impair.Mainly there is following problem in this method: the identification of (1) whole sheet and phase sequence attribute needs main frame and terminal to carry out alternately, very inconvenient when apart from each other at the scene; (2) need to increase pulse current transmitting, testing circuit, make control circui become more complicated, add cost and power consumption; (3) feature of power line carrier limits detecting distance, can not reach the theoretical detecting distance of pulse current during actual use.
In addition, China's power carrier signal frequency range is 40 ~ 500KHz.At present in low pressure kilowatt meter reading-out system, main flow carrier frequency has: lucky star journey carrier frequency dawn is about 120KHz, Rui Sikang carrier frequency is about 130KHz, and more sub-micro carrier frequency is about 115.2KHz; And traditional platform built-in testing instrument carrier frequency is generally 127KHz, close with low pressure kilowatt meter reading-out system main flow carrier frequency, its identify subscriber board sheet attribute time easily to low pressure kilowatt meter reading-out system in carrier signal transmission cause adverse effect.
Summary of the invention
Technical matters to be solved by this invention is being: for prior art Problems existing, proposes a kind of platform sheet relation detection method of unidirectional identification, and step is simple, is easy to realize, can evades " getting lines crossed " phenomenon well.
The technical scheme that the present invention solves its technical matters is as follows:
