Abstract
The invention discloses a relay calibration instrument. The calibration instrument comprises a relay installation pedestal, a first switch, a rectifying device and a timer. When a relay is tested, the tested relay is inserted into the corresponding relay installation pedestal; the first switch is closed; an alternating current power supply provides power for the whole calibration instrument; and an alternating current is converted into a direct current through the rectifying device so as to provide power for the timer. At the same time, a coil of the tested relay is energized, the timer is triggered to start to carry out timekeeping and coil energization time of the tested relay is recorded. After a period of time is delayed, a normally-open contact of the tested relay is closed, the timer is triggered to stop timekeeping and normally-open contact closing time of the tested relay is recorded. The timer calculates and acquires motion time of the tested relay according to the normally-open contact closing time and the coil energization time. Through comparing the motion time acquired through calculation and standard motion time, whether the tested relay is qualified can be determined.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the invention discloses a kind of relay checking instrument, to realize the time accuracy testing efficiency to relay
Raising.
See Fig. 1, the structural representation of a kind of relay checking instrument disclosed in the embodiment of the present invention, including: relay is pacified
Dress base 10, first switchs 1DK, fairing 11 and timer 12.
Wherein:
Relay mounting seat 10 is used for installing measured relay.Relay mounting seat 10 can be a mounting seat
Or the multiple mounting seat being connected in parallel, the number of mounting seat concrete according to being actually needed depending on, the present invention does not does at this
Limit.
Wherein, the type of measured relay can be any, such as unbalanced three-phase lines relay.
When relay mounting seat 10 is multiple mounting seat being connected in parallel, each mounting seat correspondence one is tested
Relay, owing to relay is generally of oval and square two kinds of shapes, therefore, accordingly can be by relay mounting seat
10 are designed to oval and square two kinds.
Referring specifically to the relay mounting seat 101 shown in Fig. 1 and relay mounting seat 102, oval relay
The corresponding measured relay 01 of mounting seat 101, the corresponding measured relay 02 of square relay mounting seat 102.
It is understood that when relay mounting seat 10 is multiple mounting seat, the present invention can be simultaneously to multiple
Relay is tested, thus substantially increases testing efficiency.
First switch 1DK is arranged on relay mounting seat 10 and the alternating current power supply (power module 20, AC shown in Fig. 1
Between 220V), and it is electric to make the coil of described measured relay obtain when Guan Bi.
Fairing 11 is connected with alternating current power supply, is used for converting alternating current to unidirectional current.
The power port of timer 12 is connected with fairing 11, and the unidirectional current exported by fairing 11 is as power supply
Power supply, the first signals collecting port of timer 12 is connected with the common port of relay mounting seat 10 and the first switch 1DK, meter
Time device 12 secondary signal gather port for measured relay (such as, the measured relay 01 shown in Fig. 1 and tested continue
Electrical equipment 02) normally opened contact connect, the first signals collecting port for gather first switch 1DK conducting time generation triggering based on
Time device 12 start the first triggering signal of timing, secondary signal gathers port and closes at the normally opened contact of measured relay for gathering
The triggering timing device 12 generated during conjunction stops the second triggering signal of timing.
The operation principle of relay checking instrument particularly as follows:
When relay is tested, by measured relay (such as, the measured relay 01 shown in Fig. 1 and tested
Relay 02) insert corresponding relay mounting seat (such as, measured relay 01 is inserted relay mounting seat 101, will
Measured relay 02 inserts relay mounting seat 102), Guan Bi the first switch 1DK, alternating current power supply is that whole tester is powered,
It is that timer 12 is powered that the rectified device of alternating current 11 is converted into unidirectional current, and meanwhile, the coil of measured relay obtains electric, meter
Time device 12 be triggered beginning timing, the coil of record measured relay obtains the electric moment, after time delay a period of time, measured relay
Normally opened contact closes, and timer 12 is triggered again stopping timing, the normally opened contact closing moment of record measured relay, timer
12 obtain the electric moment according to normally opened contact closing moment and coil, are calculated the movement time of measured relay, by calculating
The movement time and the standard operation time that obtain compare, and i.e. can determine whether that measured relay is the most qualified.
In summary, present invention eliminates the process manually building test platform, and have versatility, therefore save time province
Power, substantially increases testing efficiency.
