Description
Technical field
The utility model relates to a kind of relays with hydrogen.
Background technique
Existing relay includes shell, the reset equipped with yoke, electromagnet, armature and reset armature in shell
Spring, electromagnet are mounted on yoke, and static contact is additionally provided in shell, moving contact, moving contact and static contact are connected on armature
It is correspondingly arranged, whether is contacted to control moving contact with static contact by electromagnet band moving armature.But the relay of this structure
Device can generate flash burn contact, the service life of relay is short, and heat dissipation effect is poor when moving contact and static contact work；Moreover,
The components such as armature, yoke aoxidize in order to prevent, need that it is electroplated, seriously polluted, moreover, at high cost.
Utility model content
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of with hydrogen
Relay, it greatly improves arc extinguishings, heat dissipation performance, prolong its service life；Moreover, without to the components such as armature, yoke electricity
Resource is saved in plating, and more environmentally-friendly, internal metal parts will not be aoxidized and be corroded.
The technical solution of the utility model includes: a kind of relay with hydrogen, includes shell, is equipped with yoke, electricity in shell
Magnet, armature and the reset spring for resetting armature, electromagnet is mounted on yoke, is additionally provided with static contact in shell, on armature
It is connected with moving contact, moving contact is correspondingly arranged with static contact, it is characterised in that: the shell is equipped with stomata, fills out in shell
Filled with hydrogen, stomata position is corresponded on shell equipped with sealing.
By adopting the above technical scheme, it is filled with hydrogen into shell from stomata, finally by stomata sealing, can prevents outside hydrogen
It lets out, while preventing extraneous dust impurity from entering in shell.By being filled with hydrogen, anaerobic in such shell, arcing time in shell
Much smaller than the air arc arcing time, electric arc easy arc extinguishing in hydrogen medium, produced arc energy is again smaller than air dielectric；Again
The thermal conduction effect of person, hydrogen are good, and energy rapid cooling extends the service life of relay；Moreover, because anaerobic in shell, nothing
The components such as armature, yoke need to be electroplated, save resource, more environmentally-friendly, internal metal parts will not be aoxidized and be corroded.
The further setting of the utility model: the shell includes the pedestal of split settings and matches with pedestal fixation
The lid of conjunction, sealing is arranged between lid and pedestal.
Using above-mentioned further setting, so that good airproof performance between lid and pedestal, fixed, can prevent well
Hydrogen leaks.
The further setting of the utility model: further including having for connecting respectively with electromagnet, moving contact and static contact
The pin connect, the pedestal are equipped with the jack passed through for pin, and sealing is arranged between pin and jack.
Further it is arranged using above-mentioned, can prevents hydrogen from leaking between pin and jack.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model specific embodiment.
Specific embodiment
As shown in Figure 1, a kind of relay with hydrogen, includes shell 1, yoke 2, electromagnet 3, rank is equipped in shell 1
Iron 4 and the reset spring 5 for resetting armature 4,5 one end of reset spring are connect with armature 4, and the other end is connect with yoke 2, electromagnet
3 are mounted on yoke 2, and static contact 6 is additionally provided in shell 1, and contact 10 is connected on armature 4, and contact 10 is equipped with moving contact 7,
Moving contact 7 is correspondingly arranged with static contact 6, and the shell 1 is equipped with stomata 8, and hydrogen is filled in shell 1, is corresponded on shell 1
8 position of stomata is equipped with sealing；The shell 1 includes the pedestal 11 of split settings and the lid with 11 secure fit of pedestal
12, lid 12 can also be fixed, between lid 12 and pedestal 11 with pedestal 11 using snapping connection using modes such as bolts
Sealing setting；Relay further includes the pin 9 having for being separately connected with electromagnet 3, moving contact 7 and static contact 6, described
Pedestal 11 is equipped with the jack 111 passed through for pin 9, and sealing is arranged between pin 9 and jack 111.
By being filled with hydrogen, anaerobic in such shell 1 in shell 1, the arcing time is much smaller than air arc arcing time, electricity
Arc easy arc extinguishing in hydrogen medium, produced arc energy is again smaller than air dielectric；Furthermore the thermal conduction effect of hydrogen is good, energy
Rapid cooling extends the service life of relay；Moreover, because anaerobic in shell 1, without to the components such as armature 4, yoke 2 electricity
Resource is saved in plating, and more environmentally-friendly, internal metal parts will not be aoxidized and be corroded.
The inflation method of the above-mentioned relay with hydrogen, at least includes the following steps:
(1) stomata 8 is processed on the shell of relay 1；
(2) relay in the first step is put into confined space, it is vacuumized；
(3) after the completion of vacuumizing, hydrogen is filled with into confined space, so that pressure and external atmosphere pressure in confined space
Power is identical；
(4) relay after hydrogen will be filled with to take out, to position between 8 position of stomata, lid and pedestal and pin with
Jack position carries out sealing.
In inflation, it is necessary to first to vacuumizing in shell 1, then, hydrogen is filled with into the shell 1 of vacuum, and protect
It is identical as external atmospheric pressure to hold interior of shell pressure, in this way in subsequent sealing, hydrogen is not easy to leak.
Claims (3)
