The invention discloses a kind of Portable DC STS system test set, it includes the housing with upper lid and handle；Direct current binding post is provided with housing and binding post is exchanged；Direct current binding post and exchange binding post are connected with inducer and capacitor by dc circuit breaker and AC circuit breaker respectively；Inducer and capacitor are connected with ammeter respectively；Ammeter is connected with the trimmable resistance with voltmeter by wire；Trimmable resistance is connected with output wiring terminal.When needing to carry out DC system grounding to patrol and examine test, connect straight-flow system feeder assembly using direct current binding post, output wiring terminal ground connection adjusts trimmable resistance, you can change grounding resistance, tested；When needing to carry out exchange string people's direct current function test, using exchange binding post connection alternating current power supply, output wiring terminal connection straight-flow system feeder assembly, trimmable resistance is adjusted, you can change grounding resistance, tested.
Description
Technical fieldThe invention belongs to straight-flow system Insulation Test technical field, and in particular to a kind of DC system grounding of testing patrols and examines the assay device with the AC in the DC monitoring function.
Background technologyAt present, there is no the assay device patrolled and examined comprising ground connection for transformer station direct current system type insulation monitoring system with the AC in the DC repertoire.Now commonly used to ground connection inspection function method of testing is to be directly grounded to test using insulation fine copper wire; this method is relatively simple; but easily cause straight-flow system unprotect to be directly grounded; when in misoperation or touching alternating current power supply by mistake; straight-flow system can be caused to burn, stop transport, affect straight-flow system safe and stable operation.The insulation-monitoring function of the AC in the DC system is at present without assay device; the method of conventional series resistor; alternating current power supply is incorporated to into straight-flow system directly; wiring easily causes short circuit; and alternating current power supply can not be controlled, easily causing that straight-flow system AC compounent is too high, device burns, stops transport; accumulator activity is damaged, and protective relaying device malfunction is caused when serious.Said method is simple, it is impossible to Adjustment Tests precision, leans on full testing crew experience, and dangerous high, there is potential safety hazard.
The content of the inventionPresent invention aim to address prior art has the low technical problem with poor stability of test accuracy, there is provided a kind of Portable DC STS system test set, the deficiencies in the prior art are overcome.
To achieve these goals, a kind of Portable DC STS system test set of the invention, it includes the housing with upper lid and handle；Its main points is that direct current binding post is provided with the housing and binding post is exchanged；The direct current binding post and exchange binding post are connected with inducer and capacitor by dc circuit breaker and AC circuit breaker respectively；The inducer and capacitor are connected with ammeter respectively；The ammeter is connected with the trimmable resistance with voltmeter by wire；The trimmable resistance is connected with output wiring terminal.
Present configuration rationally, be easy to make, when needing to carry out DC system grounding to patrol and examine test, connect straight-flow system feeder assembly using direct current binding post, output wiring terminal ground connection adjusts trimmable resistance, you can change grounding resistance, tested；When needing to carry out exchange string people's direct current function test, using exchange binding post connection alternating current power supply, output wiring terminal connection straight-flow system feeder assembly, trimmable resistance is adjusted, you can change grounding resistance, tested.The beneficial effects of the utility model are, it is easy to carry, simple structure, DC system grounding can not only be patrolled and examined and the AC in the DC function is tested, and solve the problems, such as that no Special test instrument, test method are dangerous high, guarantee test is simple, safe and reliable, and can Adjustment Tests precision.
Description of the drawingsFig. 1 is the structural representation top view of the present invention；
Fig. 2 is the overall structure diagram of the present invention；
Fig. 3 is the circuit theory diagrams of the present invention.
1 in figure, direct current binding post 2, exchange binding post 3, dc circuit breaker 4, AC circuit breaker 5, inducer 6, capacitor 7, ammeter 8, trimmable resistance 9, voltmeter 10, output wiring terminal 11, upper lid 12, housing 13, handle
Specific embodimentWith reference to Fig. 1, Fig. 2 and Fig. 3, the present invention it include the housing 12 with upper lid 11 and handle 13；Direct current binding post 1 is provided with the housing 12 and binding post is exchanged 2；The direct current binding post 1 and exchange binding post 2 are connected with inducer 5 and capacitor 6 by dc circuit breaker 3 and AC circuit breaker 4 respectively；The inducer 5 and capacitor 6 are connected with ammeter 7 respectively；The ammeter 7 is connected with the trimmable resistance 8 with voltmeter 9 by wire；The trimmable resistance 8 is connected with output wiring terminal 10.
, using the portable insulation shell overall package for taking lid, after encapsulation, lightweight of the present invention is little, is easy to carry for the present invention；Fixed installation AC/DC type voltmeter, AC/DC type ammeter, trimmable resistance, inducer, capacitor, dc circuit breaker, AC circuit breaker, direct current binding post, exchange binding post and output wiring terminal in housing.Connect inducer after direct current binding post connection dc circuit breaker, inducer is used to isolate of ac, forms direct current input circuit, be grounded and patrol and examine test function；Ammeter, trimmable resistance, voltmeter are attempted by trimmable resistance, finally connect output wiring terminal, form output loop；Connect capacitor after exchange binding post connection exchange stream chopper, capacitor is used for isolated DC amount, forms ac input circuit, realizes that exchange seals in test function.Direct current input circuit, ac input circuit connect output loop jointly, when needing to carry out DC system grounding to patrol and examine test, connect straight-flow system feeder assembly using direct current binding post, output wiring terminal is grounded, adjust trimmable resistance, you can change grounding resistance, tested；When needing to carry out exchange string people's direct current function test, using exchange binding post connection alternating current power supply, output wiring terminal connection straight-flow system feeder assembly, trimmable resistance is adjusted, you can change grounding resistance, tested.Direct current binding post, dc circuit breaker, inducer series connection, exchange binding post, AC circuit breaker, capacitor series connection, connect trimmable resistance, then output of connecting after ammeter is accessed after direct current input circuit and ac input circuit parallel connection, voltmeter is connected in parallel on trimmable resistance.
The present invention can not only be patrolled and examined to DC system grounding and the AC in the DC function is tested, and solve the problems, such as that no Special test instrument, test method are dangerous high, guarantee test is simple, safe and reliable, be easy to carry, simple structure, the test patrolled and examined to DC system grounding with exchange string people's function can be completed, and can Adjustment Tests precision.
