Machine realizes remote control automatic closing.In the past when testing external on-load switch performance, with reference to standard GB/T
10963.1-2005《Electric attachments household and similar site's circuit-breakers for over-current protection part 1：Open circuit for exchange
Device》, the driving capability of on-load switch is not detected, the external load of electric energy meter of interior centrally-mounted driving cannot be adapted to completely
Switch.
Invention content
To reach the driving capability of centrally-mounted driving on-load switch in detection, it is proposed that a kind of electric energy meter is opened with external load
The detection method of driving capability is closed, the driving capability for the measurement on-load switch that this method can be easy improves on-load switch in skill
Requirement in art characteristic can carry out on-load switch good and bad differentiation by the detection of this method, one is provided for testing agency
Kind test method, and on-load switch manufacturer can be supervised to improve itself manufacturing process, produce premium quality product.
It is driven with external on-load switch in order to solve the above technical problems, the technical solution adopted by the present invention is a kind of electric energy meter
The detection method of ability, includes the following steps：

Mark.
Description of the drawings
Fig. 1 is the external on-load switch driving capability detects schematic diagram of electric energy meter.
Specific implementation mode
As shown in Figure 1, the present invention discloses a kind of detection method of the external on-load switch driving capability of electric energy meter, including with
Lower step：
1）External on-load switch is required to specifications and connection box of electric energy meter, external on-load switch are interior centrally-mounted driving
Novel external on-load switch, driving current provides by electric energy meter, and electric energy meter is the external intelligent electric energy of switch that state's net is promoted
Table, first auxiliary terminal of such electric energy meter are tripping control terminal, and in normal work, the terminal and A phase voltage terminals etc. are electric
Position.
2）It is connected on electric energy meter tripping control terminal after concatenating 100k Ω resistance (± 1%) on external thread switching control
On, in 23 ± 2 DEG C of environment, applies 70%-120% rated voltages to intelligent electric energy meter, tripping terminal is made to give control line output voltage
（Apply 70%, 100%, 120% rated voltage when experiment）.
3）Electric energy meter making alive come control electric energy meter trip terminal, to external on-load switch control terminal apply control electricity
Pressure then turns off electric energy meter voltage, interval time 10s, and circulate operation investigates external on-load switch working condition, and on-load switch is answered
Energy action message 50 times, if external on-load switch is 2）In three control voltage any of which voltages under cannot normally move
Make, illustrates its driving capability deficiency, belong to substandard product, action herein refers to after on-load switch once powers on automatic closing
The process of electric tripping.
4）In 23 ± 2 DEG C of environment, concatenate 100k Ω resistance (± 1%), test voltage is adjusted to 380V, by voltage signal plus
In the control terminal of on-load switch, external on-load switch working condition is observed, if external on-load switch is after applying over-pressed voltage
Can also work normally, then illustrate its ability for having overload-resistant voltage, belong to qualified products, burnt if there is driving motor or
Irregular working phenomenon then illustrates its ability for not having overload-resistant voltage, is unable to normal operation input.
Electric energy meter disclosed in this invention is introduced into bid with external on-load switch driving capability detection method to detect, entirely
In performance detection and inspection of incoming merchandise test experience, by the test analysis of this method, underproof external on-load switch is screened
Out, it avoids the insufficient external on-load switch of part of the manufacturer's driving capability to put into operation, can be that enterprise avoids unnecessary warp
