Abstract
The utility model relates to a relay, in particular to a dustproof overcurrent ground relay. The relay comprises a body, a bracket, a contact component, contacts and a coil, wherein the coil and the contact component are fixed at the two ends of the body; the bracket is fixed at the upper end of the body; and the contacts are fixed on the contact component, and are dustproof quick acting switches. The dustproof overcurrent ground relay can protect the contacts from being influenced by dust, make good the contact of an engine control circuit, ensure the normal loading and running of an engine and improve the running reliability of the engine.
Description
Technical field
The utility model relates to a kind of relay, especially a kind of dust-proof type overcurrent earth fault relay.
Background technology
Former overcurrent earth fault relay is the bareing contact, because this contact does not have anti-dust performance, use in the area that dust storm is bigger, easy laying dust between the contact, the sand and dust of accumulation can influence the contact performance of contact, cause the contact virtual connection, thereby make the The whole control circuit contacts bad, may cause that locomotive can not load to cause machine broken.
Summary of the invention
In order to overcome between relay contact laying dust easily, the deficiency of control circuit loose contact, the utility model provides a kind of dust-proof type overcurrent earth fault relay.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dust-proof type overcurrent earth fault relay, comprise body, carriage, contact assembly, contact and coil, coil and contact assembly are fixed on the body two ends, carriage is fixed on the body upper end, contact is fixed on the contact assembly, and the contact of this relay is a quick-action switch.
According to another embodiment of the present utility model, further comprise: contact is the dust-proof type quick-action switch.
The beneficial effects of the utility model are: use dust-proof type overcurrent earth fault relay can protect contact can not influenced by sand and dust, make the locomotive control circuit contacts good, guarantee locomotive energy normal load and operation, improved the reliability of locomotive operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
1. bodies among the figure, 2. carriage, 3. contact assembly, 4. contact, 5 coils.
Embodiment
As Fig. 1 is front view of the present utility model, Fig. 2 is a vertical view of the present utility model, a kind of dust-proof type overcurrent earth fault relay, be also referred to as dust-proof type overcurrent relay or dust-proof type earth fault relay, comprise body 1, carriage 2, contact assembly 3, contact 4 and coil 5, coil 5 and contact assembly 3 are fixed on body 1 two ends, carriage 2 is fixed on body 1 upper end, contact 4 is fixed on the contact assembly 3, and the contact 4 of this relay is a quick-action switch, and contact 4 is the dust-proof type quick-action switch.
During work, carriage 2 withstands 4 cams of the contact on the contact assembly 3.When the electric current that flows through relay coil 5 surpasses set point; relay coil 5 actions; carriage 2 right-hand members are attracted downwards by coil 5; one end of top cam upwards unclamps contact 4 cams, the quick-action switch action; use dust-proof type overcurrent earth fault relay can protect contact can not influenced by sand and dust; make the locomotive control circuit contacts good, guarantee locomotive energy normal load and operation, improved the reliability of locomotive operation.
