Abstract
The utility model relates to an intelligent temperature control switch, which comprises a casing, a zero line input end, a firing line input end, a zero line output end, a firing line output end and a control switch. The intelligent temperature control switch is characterized in that an indirectly heated type temperature relay and a heating element are connected in series between the control switch and the firing line input end; the temperature changes which are caused by load physical changes are led into the indirectly heated type temperature relay through the heating element for measuring and controlling by using the shunting of the load; the distance between the switch and the load is not limited so that the mutual affect between the switch and the load is eliminated, and furthermore, the load can not has frequency-sensitive starting phenomenon because a sensing element is not directly contacted with the load. The utility model is characterized in reliable operation, simple circuits and convenient operation, and can be widely used in various electric appliances.
Description
The utility model belongs to the electric equipment field of switches, relates in particular to a kind of temperature detect switch (TDS).
At present, the switch kind of domestic production is more and more, but the overwhelming majority is a plain edition.In recent years, along with increasing of various household electrical appliance, the household lines fire incident happens occasionally, analyze reason, mostly be improper use and cause, from the switch of various electrical equipment itself, also there is following shortcoming, the one, switch can not detect voltage, electric current, temperature, the 2nd, when circuit short circuit occurs, leak electricity, when having an accident, switch can not be cut off the electricity supply automatically.
The purpose of this utility model is to provide a kind of load temperature that can detect to change, and the intelligent temperature control switch of energy control circuit break-make.
For achieving the above object, following technical scheme is provided: regular tap is generally by shell, in the shell zero, live wire input, zero, live wire output and control switch are formed, the intelligent temperature control switch on this basis, be connected in series between control switch and live wire output indirect-heating temperature relay and heater element, the contact of indirect-heating temperature relay is connected with an end of heater element.
For the ease of the unequally loaded working temperature is regulated control, be connected in parallel to potentiometer and the resistance that is cascaded at the two ends of heater element.In addition, zero, the front portion of live wire output, zero, be connected with light-emitting diode and resistance between the live wire.
The utility model intelligent temperature control switch is compared with regular tap; indirect-heating temperature relay and heater element have been increased; after inserting load; when overvoltage, overcurrent appear in load; heater element can feed back to the variations in temperature that overvoltage, overcurrent cause the indirect-heating temperature relay; make the action of indirect-heating temperature relay, circuit is disconnected, with the safety of protection load and circuit.After abnormal conditions were eliminated, the indirect-heating temperature relay can recover the power supply of circuit again.
Below in conjunction with drawings and Examples the application is described in further detail.
Fig. 1 is the plan structure schematic diagram of intelligent temperature control switch.
Fig. 2 is the circuit theory diagrams of embodiment one.
Fig. 3 is the circuit theory diagrams of embodiment two.
On the shell 1 of intelligent temperature control switch control switch 2 is arranged among Fig. 1, in Fig. 2 embodiment circuit theory diagrams, control switch 2 is connected between live wire input 3, zero line input 4 and live wire output 5, the zero line output 6, between control switch 2 and live wire output 5, be connected in series with indirect-heating temperature relay 7 and heating wire 8, can connect load between live wire output 5 and the zero line output 6.Here indirect-heating temperature relay 7 is sensing elements, after it is heated, and the generation " kick " that deforms of interior metal sheet, and promote inner contact and separate, reach the purpose of cutting off circuit; Heating wire 8 is heater elements; its end is connected with an end of indirect-heating temperature relay 7; because heating wire 8 is to be serially connected in the protected load; therefore can set the current value that passes through heating wire 8 according to the operating state of load; when circuit normally moves under nominal load; the shortage of heat that electric current produced by heating wire 8 is so that 7 actions of indirect-heating temperature relay, so circuit is kept conducting state.When short circuit, superpressure, overtemperature appear in load, will make the instantaneous increase of electric current in the circuit, surpass the current value that heating wire 8 is set, heating wire 8 heats up rapidly, impels indirect-heating temperature relay 7 to produce " kick ", and its inner contact is separated, and cuts off circuit.And when the electric current in the line load was lower than the current value of heating wire 8 settings, indirect-heating temperature relay 7 connection automatically once more recovered electric, thereby reached monitoring and protection to instrument and equipment or household electrical appliance.
The intelligent temperature control switch is to utilize the load bridging principle, the physical change of load guided to carry out observing and controlling in the switch, the distance of switch and load is unrestricted, has eliminated influencing each other between switch and the load, because sensing element does not directly contact with load, load does not have the Fraquent start phenomenon in addition.
In the circuit diagram of Fig. 3 embodiment two, the two ends of heating wire 8 are parallel with potentiometer 9 and resistance 10, are for the ease of setting the current value of heating wire 8, can adjusting according to the different situations of load.In order to make switch working state directly perceived, zero, the front portion of live wire output 5,6, zero, be connected to light-emitting diode 11 and current-limiting resistance 12, switch conduction, led lighting between the live wire; Switch disconnects, and diode extinguishes.
Intelligent temp-controlled switch may be used on various resistive, inductive is daily In electrical equipment, the temperature control device, serviceability temperature can be regulated arbitrarily, even the city Electricity instability, superpressure, overcurrent, overtemperature can both reliably be cut off the electricity supply, Have reliable operation, circuit is simple, characteristics easy to use.
