Abstract
The invention discloses an improved structure of a control circuit of a tin furnace heater; the control circuit is controlled by alternating current contactors; two alternating current contactors are arranged and serially connected; even if one alternating current contactor loses effect, the other contactor can ensure the normal work of the tin furnace heater, so that one more layer of protection is provided for the tin furnace heater; and meanwhile, fire can be effectively prevented.
Description
Technical field
The present invention relates to a kind of tin stove heater that can be used for industry heating, be 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.
Summary of the invention
In order to overcome defects; the invention provides a kind of tin stove control circuit for heater structure-improved; tin stove control circuit for heater structure-improved of the present invention 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 present invention 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 invention has the beneficial effects as follows: tin stove control circuit for heater structure-improved of the present invention 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 invention.
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)
1. tin stove control circuit for heater structure-improved, its control circuit is controlled by A.C. contactor, it is characterized in that: described A.C. contactor (1) is two and series connection.
