Specific embodiment
The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.
As shown in Figures 1 to 4, a kind of high current three-phase and four-line temperature controller described in the utility model, including temperature controller case
3, temperature controller case 3 is interior to be separated into upper chamber and lower cavity by partition 30, and connecting terminal 1 is equipped in upper chamber, is moved
Contact 9 and movable plate 5, movable contact spring 9 drive the movable contact 7 and connecting terminal that move up and down and realize on movable contact spring 9 by movable plate 5
Connection and disconnection between 1, lower cavity is interior to be equipped with bimetal leaf 10, and the side of movable plate 5, which is equipped with, resets push rod 50 and porcelain knob
51, the other side of movable plate 5 is equipped with connecting rod 52, and the through-hole that connecting rod 52 passes through on partition 30 contacts at the setting of bimetal leaf 10, moves
Contact 9 is fixed on porcelain knob 51, and spring 8 is equipped between movable contact spring 9 and the top of temperature controller case 3, and spring 8 is placed on porcelain knob 51
On, and the elastic force of spring 8 must be less than the elastic force of bimetal leaf 10.The above constitutes the utility model basic structure.
The utility model uses such structure setting, working principle: temperature controller case 3 and high-power electric appliance equipment connect
After connecing, control temperature is preset, when the temperature of high-power electric appliance equipment reaches preset temperature, it is intracorporal double to be set to lower chamber
Raising upward 10 moment of sheet metal, (when temperature controller is in the initial stage, bimetal leaf 10 is to be arranged to recessed, such as Fig. 2 institute
Show), to jack up movable plate 5 by connecting rod 52, drive reset push rod 50 upward together with porcelain knob 51 when movable plate 5 moves up
Movement drives movable contact spring 9 upwards by porcelain knob 51, to make separated (four of the movable contact 7 and connecting terminal 1 on movable contact spring 9
The contact of synchronous eight connecting terminals 1 of movable contact 7 on movable contact spring 9 on root porcelain knob 51 is detached from), three-phase and four-line is synchronous to be disconnected,
The circuit of high-power electric appliance equipment is caused to disconnect, to realize that high-power electric appliance equipment stops the effect of heating；When high-power electricity
When device device temperature is lower than preset temperature (movable contact spring 9 will not reset, always in separated with connecting terminal 1), only when passing through
When manually actuated reset push rod 50, when power is more than the elastic force of bimetal leaf 10, the weight under the elastic force effect of spring 8 of movable contact spring 9
New reset electrically connects with connecting terminal 1, to make circuit communication.The utility model can realize that the overheat of high-power electric appliance equipment is protected
Shield can be realized the electricity of primary open or closed three-phase and four-line, and synchronism is good, and big by electric current, use scope is extensive.
It should be noted that the elastic force of spring 8 is necessarily less than the elastic force that bimetal leaf 10 pops up.
In practical application, the center for resetting push rod 50 and being set to 5 side of movable plate resets the two sides point of push rod 50
Not She You two porcelain knobs 51 (totally four porcelain knobs 51), reset push rod 50 and four porcelain knobs 51 in straight line setting, and each
The two sides of porcelain knob 51 are respectively equipped with connecting terminal 1 (totally eight connecting terminals 1), and the movable contact spring 9 being fixed on porcelain knob 51 passes through porcelain
