||1) Functions, features and use
At present, our country electric power systems in addition
to charge power metering device which charge when measuring
fees, even according to levy a loss of power transformer
capacity meritorious and reactive power loss of subsidies.
For larger users in transformer substation even pay extra
fees in one time. Therefore, in the capacity of transformer
testing for both sides is to maintain with economic interests
is an important link. Due to energy shortage, electricity
price rise, some users by interest drives to replace transformer
nameplate large capacity transformer filling small capacity
transformer, fled leakage power add cost.
HRRC type transformer capacity parameters tester is used
exclusively in low voltage, low current circumstance standard
test power transformer capacity distribution of instruments.
This instrument circuit design is exquisite, the thought
is unique, superior performance, powerful, completely satisfy
field distribution power transformer capacity test requirements.
This instrument internal adopts advanced A/D synchronous
communication sampling and digital signal processing technology,
the operation is simple, convenient, reliable data accurate
wiring, solve the difficult problem of distribution transformer
capacity test, and can display, print users concerned measurement
data. Use this instrument can greatly improve the working
efficiency and relieve labor intensity.
The equipment is mainly used for distribution transformer
capacity detection, in not external voltage, current transformer,
under the situation of single can be directly below the
complete 1000kVA distribution transformers in all the voltage,
current capacity test under the condition of all. The equipment
adopts single-phase three-phase experiment test power supply
mode and power transformer capacity way of measuring ways.
Single-phase power test is especially useful in field without
power supply conditions of use, only need to bring a single-phase
generator and the equipment that can be completed test.
This equipment in order to more practical at the scene,
minimize test power supply capacity; In the transformer
10% of the rated power flow can be measured the transformer
capacity, which means small generator can complete the large
capacity transformer capacity detection.
The instrument of man-machine interface using CHKDSK (240
* 128) all Chinese characters graphic display, menu strictly
hierarchical, gradually guide you through the experiment,
you only need to boot, press any key and instrument provides
menu will guide you through the test of what you need.
