Abstract
The utility model discloses a clamp type voltage-ampere phase meter jaw device, and solves the problem that large amount of electric power is consumed because of idling when a newly-built load transformer or a circuit is used for the first time. The device comprises a current transformer terminal corresponding terminal plug (1), a corresponding terminal single-turn soft wire (2), a jaw body (3), a non-corresponding terminal single-turn soft wire (4), and a current transformer terminal non-corresponding terminal plug (5). One end of the corresponding terminal single-turn soft wire (2) is connected to a corresponding terminal (6) of the jaw body (3), and the non-corresponding terminal single-turn soft wire (4) is connected to a non-corresponding terminal (7) of the jaw body (3). Eleven turns of wire, which can magnify the signals by eleven times, are arranged in the inner of a left jaw mouth position (8). An upper jaw mouth position (9), a right jaw mouth (10) and a lower jaw mouth (11) are all provided with ten turns of wire, which can magnify the signals by tem times. The clamp type voltage-ampere phase meter jaw device has the advantages of saving a large amount of electric energy and guaranteeing safe running of the electric power network.
Description
Technical field
The utility model relates to a kind of utensil of measuring the pincers type volt-ampere phase meter of protection phasor, particularly measures the utensil of high voltage electric power equip ment protection phasor under a kind of little load.
Background technology
When newly-built load transformer or circuit drop into first, when charged first such as large-size thermal power plant startup/standby change or newly-built factories and miness transformer, need after the high voltage electric power equip ment charging, be with big load to check the differential protection phasor immediately.Could drop into primary equipment and main protection thereof after protection and table meter phasor are correct.But be with difficulty of big duty ratio after these newly-built high voltage electric power equip ments are charged first immediately, a large amount of electric driven equipments this moment (load) are being installed or are being installed because there not being power supply not carry out debugging usually.If at this moment organize a large amount of electric driven equipments rotating operation when not debugging, not only easily cause the device damage accident, also because idle running consumes a large amount of electric energy, also may cause power equipment accident impact power system security.
Summary of the invention
The utility model provides a kind of pincers type volt-ampere phase meter jaw device, has solved when newly-built load transformer or circuit drop into first, consumes the problem of a large amount of electric energy because of idle running.
The utility model overcomes the above problems by following scheme:
A kind of pincers type volt-ampere phase meter jaw device comprises current transformer terminal end plug of the same name, end single turn flexible circuit conductor of the same name, jaw body, non-same polarity single turn flexible circuit conductor, current transformer terminal non-same polarity plug.The jaw body is formed by the coiling of multiturn insulated conductor.Inside comprises, jaw body end of the same name, jaw body non-same polarity, left jaw, upper jaw, right jaw and lower jaw.The table pincers of pincers type volt-ampere phase meter can choose a place wantonly in left jaw, upper jaw, right jaw, these four positions of lower jaw or many places are measured.One end of end single turn flexible circuit conductor of the same name is connected with the end of the same name of jaw body, and non-same polarity single turn flexible circuit conductor is connected with the non-same polarity of jaw body.Jaw position inside, a left side is provided with 11 circle leads, can amplifying signal 11 times.All there are ten circle leads the inside of upper jaw, right jaw, lower jaw, can amplifying signal ten times.The table pincers of pincers type volt-ampere phase meter can choose a place wantonly in left jaw, upper jaw, right jaw, these four positions of lower jaw or many places are measured.The current transformer terminal plug is used for reliably being connected with the current transformer terminal jacks, and the single turn flexible circuit conductor can make things convenient for the traverse measurement of jaw body.Earlier the current transformer plug of jaw device is inserted into the jack at current transformer terminal two ends during measurement, turn-off current mutual inductor terminal is middle in flakes again.Measurement finishes the back, and connection current transformer terminal is middle in flakes earlier, extracts the current transformer plug of jaw device again.For three-phase system, adopt the jaw device of 4 identical structures to be made of one the direction unanimity.Represent A, B, C, N phase respectively.
The utility model provides a kind of high voltage electric power equip ment charged difficult problem that needs a large amount of loads of tissue carry out phasor measurement first that solves, and can require the correctness of check protection phasor under the load condition below 10% of load in routine, early equipment is put into operation.Not only can avoid device damage, also can save a large amount of electric energy, to guarantee electric power netting safe running.
