Description
Technical field
This utility model relates to the automatic paragraphing switch limit low-voltage measuring instrument of a kind of limit low-voltage utilizing the voltmeter record automatic paragraphing switch separating brake moment。
Background technology
After intelligent network distribution transformation, 10kV circuit being mounted with, a number of automatic paragraphing switchs, finishes the mode of fault whole piece circuit interruption maintenance at, it is achieved that the function of circuit load-shedding；Meanwhile, automatic paragraphing switch switchs with the main line in transformer station and matches, and completes localization of fault and isolation.Automatic paragraphing switch is made up of controller and Switch main body, and controller plays the effect controlling Switch main body deciliter state.When major network changes of operating modes is relatively big, bus near-end three-phase metallic short circuit time, distribution line there will be the situation that voltage is relatively low, the voltage that controller collects also step-down, its output to Switch main body electric current diminish the most accordingly, the suction-combining force of coil reduces, causing Switch main body separating brake, this automatic paragraphing following circuit of switch, by dead electricity, causes the power failure unnecessary to user.Therefore, it is necessary to the limit low-voltage of clear and definite automatic paragraphing switch, grasp distribution voltage operation level in real time, adjust the method for operation in time, maintain rational automatic paragraphing switching voltage range of operation.
By retrieval, have not yet to see the report of the limit low voltage devices utilizing the voltmeter record automatic paragraphing switch separating brake moment.
Summary of the invention
The purpose of this utility model is to provide the automatic paragraphing switch limit low-voltage measuring instrument of a kind of limit low-voltage utilizing the voltmeter record automatic paragraphing switch separating brake moment.
In order to reach object above, this utility model be the technical scheme is that this automatic paragraphing switchs limit low-voltage measuring instrument, including automatic paragraphing Switch main body, aviation plug male, aviation plug female and controller, aviation plug male and aviation plug female are connected by jacket cables, aviation plug male and automatic paragraphing Switch main body female grafting, aviation plug female and the male grafting of controller, it is characterized in that: the power supply of described controller draws conductor in parallel voltmeter, a piece lead-out wire of voltmeter is connected with one end of slide rheostat, another root lead-out wire of voltmeter connects conductor slide block, conductor slide block touches the surface of slide rheostat, simultaneously, the two ends parallel connection 220V alternating current power supply of slide rheostat；220V alternating current power supply provides working power for controller, and slide rheostat changes, by changing the position of conductor slide block, the running voltage being input in controller, and voltmeter is used for measuring and record the running voltage being input in controller.
This utility model is implemented also by following measure: described slide rheostat is arranged in a casing, and voltmeter is located at the front face top of casing, and the shank of conductor slide block is insulation handle, and insulation handle stretches out from the bar hole of casing.
Described slide rheostat is prior art, therefore seldom states.
Described aviation plug male and aviation plug female are Cabling Standard part, can use GX16 type 6 core female, GX16 type 10 core male；Jacket cables correspondingly is also standard component, and can to use model be RVV, specification is the jacket cables of 15*0.3.
The beneficial effects of the utility model are: this automatic paragraphing switch limit low-voltage measuring instrument, its properly functioning voltage range can be provided, avoid automatic paragraphing switch working voltage less than its limit low-voltage, cause unnecessary power failure, change for the distribution method of operation and Technical Reference is provided, and simple in construction, easy to use, it is effectively increased power supply reliability.
Accompanying drawing explanation
Fig. 1 is structure schematic front view of the present utility model.
Fig. 2 is the front-view schematic diagram of structure casing of the present utility model.
Detailed description of the invention
This utility model is made with reference to Fig. 1, Fig. 2.This automatic paragraphing switch limit low-voltage measuring instrument, including automatic paragraphing Switch main body 1, aviation plug male 2, aviation plug female 3 and controller 4, aviation plug male 2 and aviation plug female 3 are connected by jacket cables 5, aviation plug male 2 and automatic paragraphing Switch main body 1 female grafting, aviation plug female 3 and the male grafting of controller 4, the folding of automatic paragraphing Switch main body 1 is realized by controller 4, it is characterized in that: the power supply of described controller 4 draws wire 6 shunt voltage table 7, a piece lead-out wire of voltmeter 7 is connected with one end of slide rheostat 9, another root lead-out wire of voltmeter 7 connects conductor slide block 8, conductor slide block 8 touches the surface of slide rheostat 9, simultaneously, the two ends parallel connection 220V alternating current power supply of slide rheostat 9；220V alternating current power supply provides working power for controller 4, and slide rheostat 9 changes, by changing the position of conductor slide block 8, the running voltage being input in controller 4, and voltmeter 7 is used for measuring and record the running voltage being input in controller 4.
As improvement of the present utility model: described slide rheostat 9 is arranged in a casing 10, and voltmeter 7 is located at the front face top of casing 10, the shank of conductor slide block 8 is insulation handle 11, and insulation handle 11 stretches out from the bar hole 12 of casing 10；So can be easy to carry.
Described slide rheostat 9 is prior art, therefore seldom states.
Described aviation plug male 2 and aviation plug female 3 are Cabling Standard part, can use GX16 type 6 core female, GX16 type 10 core male；Jacket cables 5 correspondingly is also standard component, and can to use model be RVV, specification is the jacket cables of 15*0.3.
When using this utility model, after first each equipment being connected, connect 220V power supply, then regulate the conductor slide block 8 position on slide rheostat 9 by pulling insulation handle 11, make controller 4 voltage reach 220V；Then, slowly make conductor slide block 8 along slide rheostat 9 slide downward, make controller 4 voltage be gradually reduced therewith, observe deciliter state of Switch main body 1 simultaneously.When controller 4 voltage is reduced to a certain value, separating brake, on off state by display point position, are simultaneously emitted by mechanism's separating brake sound, the at this moment numerical value in recording voltmeter 7 by Switch main body 1, and this numerical value is automatic paragraphing switch limit low-voltage.
