Description
Technical field
The present invention relates to the detection method by external on-load switch driving force for a kind of electric energy meter.
Background technology
Expense control intelligent electric energy meter is a type electric energy meter important in the intelligent electric energy meter that State Grid Corporation of China promotes, its
In be divided into again on-load switch built-in with the external electric energy meter of on-load switch, external on-load switch electric energy meter needs configuration when normal use
External on-load switch.For the most-often used single-phase intelligent electric energy meter of resident, external on-load switch is small-sized open circuit
Device, according to State Grid Corporation of China to the electric energy meter functional requirement of external on-load switch, increases in miniature circuit breaker and drives electricity
Machine realizes remotely controlling automatic closing.In the past when external on-load switch performance is tested, with reference to standard GB/T
10963.1-2005 " electric attachments family expenses and similar site circuit-breakers for over-current protection part 1: for the open circuit of exchange
Device ", the driving force of on-load switch is not detected, it is impossible to the external load of electric energy meter of centrally-mounted driving in adapting to completely
Switch.
Content of the invention
For reaching to detect the driving force of built-in driving motor load switch, it is proposed that a kind of electric energy meter is opened by external load
Close the detection method of driving force, the driving force of the measurement on-load switch that the method can be easy, improve on-load switch in skill
Requirement in art characteristic, can be carried out the differentiation of quality by the detection of the method to on-load switch, provides one for testing agency
Plant method of testing, and on-load switch manufacturer can be supervised to improve self manufacturing process, produce premium quality product.
For solving above-mentioned technical problem, the technical solution used in the present invention is that a kind of electric energy meter is driven by external on-load switch
The detection method of ability, comprises the following steps:
1) external on-load switch is required and connection box of electric energy meter to specifications.
2) series resistor on the control line, and control line is connected on electric energy meter tripping operation control terminal.
3) control electric energy meter tripping operation terminal, apply control voltage to external on-load switch control line, investigate external load and open
Close duty.
4) on the control line of series resistor, apply overvoltage voltage, observe external on-load switch duty.

Further, described overvoltage voltage is 380V.
Use and provide the benefit that produced by technique scheme:
Detection technique adds the external on-load switch driving force test method of electric energy meter, on-load switch performance is proposed
Higher requirement, is finally reached raising on-load switch quality, allows users to use the target of upper safe and reliable product.
Brief description
Fig. 1 is electric energy meter external on-load switch driving force detection schematic diagram.
Detailed description of the invention
As it is shown in figure 1, the present invention discloses the detection method by external on-load switch driving force for a kind of electric energy meter, including with
Lower step:
1) requiring and connection box of electric energy meter external on-load switch to specifications, external on-load switch is the new of interior centrally-mounted driving
The external on-load switch of type, its driving electric current is provided by electric energy meter, and electric energy meter is the external intelligent electric energy meter of switch that state's net is promoted, this
Planting first auxiliary terminal of electric energy meter is tripping operation control terminal, this terminal and A phase voltage terminal equipotential when normal work.
2) it is connected on electric energy meter tripping operation control terminal after concatenating 100k Ω resistance (± 1%) on external thread switching control
On, in 23 ± 2 DEG C of environment, apply 70%-120% rated voltage to intelligent electric energy meter, make tripping operation terminal to control line output voltage
(during test, applying the 70%th, the 100%th, 120% rated voltage).
3) electric energy meter making alive controls electric energy meter tripping operation terminal, applies control electricity to external on-load switch control end
Pressure, turns off electric energy meter voltage subsequently, and 10s, circulated operation and investigated external on-load switch duty interval time, and on-load switch should
Can action message 50 times, if external on-load switch is 2) in three control voltages any of which voltages under can not normally move
Making, illustrating that its driving force is not enough, belong to substandard product, action herein refers to on-load switch once to power on after automatic closing to fall
The process of electric tripping.
4), in 23 ± 2 DEG C of environment, concatenation 100k Ω resistance (± 1%), test voltage is adjusted to 380V, adds voltage signal
At the control end of on-load switch, observe external on-load switch duty, if external on-load switch is after applying overvoltage voltage
Can also normally work, then illustrate that it possesses the ability of overload-resistant voltage, belong to qualified products, if there is drive burn-down of electric motor or
Irregular working phenomenon, then illustrate that it does not possess the ability of overload-resistant voltage, it is impossible to normal operation input.
The external on-load switch driving force detection method of electric energy meter disclosed in this invention is incorporated into bid detect, entirely
In performance detection and inspection of incoming merchandise test experience, by the test analysis of the method, underproof external on-load switch is screened
Out, it is to avoid the not enough external on-load switch of part producer driving force puts into operation, can avoid unnecessary warp for enterprise
Ji loss and and user between trade dispute.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
