Description
Technical field
This utility model relates to a kind of power-factor meter, is specifically related to a kind of power-factor meter with metering interface, and having can On line inspection and original position function of measuring.
Background technology
SD110-83 " electrical measurement reading instument inspection procedure " regulation that is accurate for guaranteeing the power-factor meter numerical value in using, that issue according to Ministry of Water Resources and Electric Power of the People's Republic of China (PRC), needs to examine and determine power-factor meter, and the cycle is 1 year.Calibrating main project includes: visual examination, calibra tion, the calibrating of difference between rising and falling.
Currently, power-factor meter the most do not detect interface, testing staff can only shut down, power-off, is removed and delivers to measurement technology mechanism by verification worker at laboratory verification, qualified after fetch installation again.During this, shutdown power-off, dismounting power-factor meter, road transport not only consume substantial amounts of manpower, financial resources and time, it is also possible to can bring the fault of equipment and power-factor meter because of dismounting.Additionally, the most especially return in way especially can owing to jolting, the reason such as vibration increase the probability of malfunction of power-factor meter.Even if field environmental condition meets vertification regulation requirement, user of service is also required to shutdown, power-off, the connecting line of disconnection power-factor meter binding post and equipment are examined and determine.
Meanwhile, when twice period of tracing to the source suspects that power-factor meter video data is problematic, also can only shut down power-off, disconnection power-factor meter binding post checks with the connecting line of equipment, can consume certain manpower, financial resources and time equally.
Summary of the invention
The purpose of this utility model is to provide a kind of power-factor meter with metering interface, to overcome the deficiencies in the prior art, reduces and uses unit manpower, financial resources and time loss, improves equipment by rate.
A kind of power-factor meter with metering interface, including measuring mechanism, it is characterized in that this measuring mechanism is connected with electronic surveying circuit, described electronic surveying circuit is connected with binding post A, binding post B binding post C, post D, binding post E, binding post F and binding post G respectively；Between electronic surveying circuit to binding post A, wherein it is sequentially provided with jack A, switch A, jack B, jack C, switch B it is sequentially provided with between electronic surveying circuit to binding post B, jack D, switch C, jack E it is sequentially provided with between electronic surveying circuit to binding post C, jack F, switch D it is sequentially provided with between electronic surveying circuit to post D, it is provided with jack G between electronic surveying circuit to binding post E, between electronic surveying circuit to binding post F, it is provided with jack H, between electronic surveying circuit to binding post G, is sequentially provided with jack I, switch E.
The above-mentioned power-factor meter with metering interface, also includes multiple blocking, described jack A, jack B, jack C, jack D, jack E, jack F, jack G, jack H and jack I, plug for seal when not using.
The above-mentioned power-factor meter with metering interface is carried out On line inspection or the method for metering in situ, it is characterised in that comprise the following steps:
(1) switch A, switch B, switch C, switch D, switch E are placed in the state of "off"；
(2) blocking is taken off, by jack A, jack B, jack D, jack E, jack G, the external high-grade power-factor meter of jack H (10), jack I or standard scale；
(3) switch B, switch D, switch E are placed in the state of " closed ", realized this with the inspection under current state of the power-factor meter of metering interface by external high-grade power-factor meter, or by external standard scale realization to this with the metering of the power-factor meter of metering interface；
(4) switch B, switch D, switch E are placed in the state of "off", take off high-grade power-factor meter or standard scale, block blocking；
(5) switch A, switch B, switch C, switch D, switch E are placed in the state of " closed ", normally should work with the power-factor meter of metering interface.
This utility model devises nine fixed end electric connectors and two switches on power factor watch shell, it is to avoid dismounting censorship even disconnects the problem that ray examination produces, thus realizes On line inspection and metering in situ.Realized the break-make of measurement circuitry by shift knob with the power-factor meter of metering interface, the metering (inspection) of power-factor meter in the case of instrument is not dismantled, can be completed by measuring the external standard scale of jack (high-grade power-factor meter).Can improve productivity effect on the premise of ensureing equipment safety, table is easy to use, simple to operate.
