Abstract
The utility model discloses a solder machine heater control circuit improved structure. A control circuit is controlled through alternating current contactors. The number of the alternating current contactors is two. The alternating current contactors are in series connection. Even if one alternating current contactor loses efficiency, the other alternating current contactor can ensure normal working of a solder machine heater, and therefore one more layer of protection is provided for the solder machine heater and meanwhile a fire disaster is effectively prevented from occurring.
Description
Technical field
The utility model relates to a kind of tin stove heater that can be used for industry heating, is specifically related to a kind of tin stove control circuit for heater structure-improved.
Background technology
Tin stove heater is a kind of to be machine for industrial molten tin, only have the work of an A.C. contactor control machine in the control circuit of the tin stove heater of prior art, because tin stove self-temperature is very high, cause easily A.C. contactor to damage, both cause production loss, also had potential safety hazard.
The utility model content
In order to overcome defects; the utility model provides a kind of tin stove control circuit for heater structure-improved; tin stove control circuit for heater structure-improved of the present utility model can guarantee the normal operation of tin stove heater more safely and effectively; simultaneously; the safeguard protection of many one decks also is provided for tin stove heater, has prevented that fire from occuring.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of tin stove control circuit for heater structure-improved, its control circuit is controlled by A.C. contactor, and described A.C. contactor is two and series connection.
The beneficial effects of the utility model are: tin stove control circuit for heater structure-improved of the present utility model is to be in series with two A.C. contactors at control circuit; even one of them inefficacy; another also can guarantee the normal operation of tin stove heater; the protection of many one decks is provided for tin stove heater; simultaneously, can prevent effectively that also fire from occuring.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
The specific embodiment
Embodiment: a kind of tin stove control circuit for heater structure-improved as shown in Figure 1, its control circuit is controlled by A.C. contactor, and described A.C. contactor 1 has two and by being connected in series.
Claims (1)
