Abstract
The utility model discloses a calibrator of a relay protection device, which comprises a voltage regulator. The voltage regulator is connected with a power supply and a transformer through wires, a switch is arranged on the wire between the voltage regulator and the power supply, the transformer is connected with a relay protection device through a wire, and an ammeter is arranged on the wire between the transformer and the relay protection device. The utility model has the advantages of reasonable structural design, accurate calibration of the relay protection device, prevention of electrical accident, low manufacturing cost, solid structure and the like.
Description
Technical field
The utility model relates to the relay protector field, specifically is a kind of relay protector tester.
Background technology
When high-voltage motor uses; for guaranteeing the safe operation of high-voltage motor; need regular relay protector to carry out verification to high-voltage motor; guarantee relay protector precision maneuver after reaching setting value; working value and the setting value of promptly guaranteeing relay protector are consistent, and avoid not being inconsistent the great electrical equipment accident that causes owing to relay protector working value and setting value.Usual relay protection device pick-up unit is the relay protector electronic detector on the existing market, and its complex structure is fragile, the cost of manufacture height.
Summary of the invention
The purpose of this utility model is to provide a kind of relay protector tester, and it can solve the deficiency that exists in the known technology, and simple for structure reasonable, cost is low.
The utility model for achieving the above object; be achieved through the following technical solutions: a kind of relay protector tester; comprise pressure regulator; pressure regulator is connected with transformer with power supply by lead; on the lead between pressure regulator and power supply switch is installed; transformer is connected with relay protector by lead, on the lead between transformer and relay protector reometer is installed.
Advantage of the present utility model is: reasonable in design, and accurately the verification relay protector prevents that the electrical equipment accident from taking place; Low cost of manufacture; Not fragile etc.
Description of drawings
Accompanying drawing 1 is a main TV structure synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail for the contrast accompanying drawing:
Agent structure of the present utility model has pressure regulator 3; pressure regulator 3 is connected with transformer 4 with power supply 1 by lead; switch 2 is installed on the lead that pressure regulator 3 and power supply are 1; transformer 4 is connected with relay protector 6 by lead; reometer 5 is installed on the lead that transformer 4 and relay protector are 6; reometer 5 detects the electric current of relay protector 6, and is shown on the reometer 5.
When the utility model uses, Closing Switch 2, energized, transformer 4 is adjusted the operating voltage of voltage to relay protector 6, adjusts the power that pressure regulator 3 outputs are fit to then, makes the scheduled current that shows relay protector 6 on the reometer 5, observe the relay protector 6 of this moment, if relay protector 6 actions illustrate that then relay protector 6 is working properly, relay protector 6 working values are consistent with setting value; If relay protector 6 is failure to actuate; variation has taken place in the action setting value that relay protector 6 then is described; need the working value of relay protector 6 is readjusted definite value, and then repeat above-mentioned steps and carry out verification, consistent up to the working value of relay protector 6 with setting value.
