Preferably, verifying power supply is 24 volts of DC power supplies.
Preferably, calibration equipment is used to while verifying 6 relays.
Compared with prior art, the invention has the following beneficial effects: by connecing the normally opened or normally closed of each relay
Point is cascaded respectively, without their on-off of independent measurement, can be fed back by indicator light, reduces inspection based on interblock interference
The thought for surveying range, tentatively can quickly judge that the contact of the relay of the group is problematic.
Detailed description of the invention
Fig. 1 is the actuating circuit figure of relay in the calibration equipment of new type of relay according to the present invention；
Fig. 2 is the checking circuit figure of relay in the calibration equipment of new type of relay according to the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As depicted in figs. 1 and 2, the calibration equipment of the new type of relay of specific embodiment according to the present invention is used to same
When verify multiple relays, can verify 14 foot relays (8 foot principles are the same), each relay include four pairs of normal opened contacts and
Four pairs of normally closed contacts, the calibration equipment include action power, multiple relay bases, verifying power supply and indicator light.The present embodiment
The calibration equipment is illustrated with verifying 6 relays simultaneously.Wherein, action power is used to multiple relay offer movements
Voltage, the number of multiple relay base is consistent with the number of multiple relays to be verified, and multiple relay bases are arranged side by side
Action power is accessed, relay base is used to install relay to be verified.The movement electricity of relay is shown in conjunction with Fig. 1, Fig. 1
Road, relay K1-K6 includes four pairs of normal opened contacts and four pairs of normally closed contacts, by the relay base parallel connection of 6 relay K1-K6
Together, it is connected on relay protection instrument, relay protection instrument can use an adjustable direct current 24V power supply and voltmeter interim generation
It replaces, in addition access is spaced apart QF2 in actuating circuit.
As shown in Fig. 2, Fig. 2 shows the checking circuits of all normal opened contacts of relay and all normally closed contacts.It is multiple
All normal opened contacts and all normally closed contacts of relay access verifying power supply, the series circuit of normal opened contact after concatenating respectively
It neutralizes in the series circuit of normally closed contact and is respectively connected to indicator light, in conjunction with Fig. 2, in the series circuit of the normal opened contact of relay K1
Indicator light H1 is accessed, accesses indicator light H7 in the series circuit of the normally closed contact of relay K1, the normal opened contact of relay K2
Indicator light H2 is accessed in series circuit, accesses indicator light H8 in the series circuit of the normally closed contact of relay K2, relay K3's
Indicator light H3 is accessed in the series circuit of normal opened contact, accesses indicator light H9 in the series circuit of the normally closed contact of relay K3,
Indicator light H4 is accessed in the series circuit of the normal opened contact of relay K4, is accessed in the series circuit of the normally closed contact of relay K4
Indicator light H10 accesses indicator light H5, the series connection of the normally closed contact of relay K5 in the series circuit of the normal opened contact of relay K5
Indicator light H11 is accessed in circuit, accesses indicator light H6 in the series circuit of the normal opened contact of relay K6, relay K6's is normally closed
Indicator light H12, the indicator light in the series circuit where normal opened contact, such as indicator light are accessed in the series circuit of contact
Indicator light in the series circuit of H1 or normally closed contact does not work, such as indicator light H7, then the series electrical where the indicator light not worked
All normal opened contacts or all normally closed contacts in road are judged as all unqualified.That is, such as indicator light H1 does not work, then
Normal opened contact 5,6,7,8 is judged as unqualified simultaneously.When specific detection, when not giving relay making alive, H7-H12 indicator light is bright,
If some indicator light is non-lit up, the normally closed contact of the relay is problematic；After actuating circuit is powered, power-up is depressed into relay
Device movement, H1-H6 indicator light can be lighted at this time, if plus operation voltage indicator light it is non-lit up, which has
Problem.In this way, can tentatively judge that the contact of the relay of the group is problematic, then detects the relay of the group one by one with multimeter
The on-off of the contact of device, the final verification for realizing relay.
Why the calibration equipment of the present embodiment is designed in this way, and is the thought that detection range is reduced based on interblock interference.Cause
For under normal circumstances, the probability of failure is very low, the range that can be broken down in this way by grouping with quick lock in, Er Qiecao
Make simple, the on-off for judging the contact of relay by the way that whether indicator light is lighted.If indicator light does not work, the group is tentatively judged
Relay contact it is problematic, then combine multimeter, detect one by one.The purpose of grouping is to reduce detection range.
Embodiment as one preferred, relay to be verified be used to be inserted on relay base, relay with after
Electric appliance pedestal is electrically connected by plug.
Embodiment as one preferred, action power are 24 volts of DC power supplies or 220 volts of direct currents or 220 volts of alternating currents
Source.
To sum up, the calibration equipment of the new type of relay of the present embodiment, by by the normally opened or normally closed contact of each relay
It is cascaded, without their on-off of independent measurement, can be fed back by indicator light respectively, need two people single compared to original
Relay is verified, and each contact goes to measure, which can largely shorten the verification relay time, and cost of manufacture is small,
Verification is reliable.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
