Abstract

The invention discloses a delay current setting and regulating mechanism for a circuit breaker and comprises a base 1, a static contact 2, an arc quenching chamber 3, a transmission mechanism 4, a cover 5, a handle 6, a knob 7, a traction bar 9, a spring 10, a binding screw 11, a wiring block 12, an adjusting screw 13 and a temperature sensing element 14, wherein, the base 1 is provided with the transmission mechanism 4; the transmission mechanism 4 is provided with the traction bar 9 and the temperature sensing element 14 with the adjusting screw 13; an extension spring 10 is arranged between the traction bar 9 and the temperature sensing element 14; and the rotation of the traction bar 9 is controlled by the spring 10. The invention is characterized in that an adjusting rod 8 is additionally arranged on the traction bar 9; the adjusting rod 8 is inserted into the concave slots at both ends of the traction bar 9; the cover 5 is provided with the knob 7; and the knob 7 is inserted into a lug boss 15 of the adjusting rod 8. When the knob is rotated to adjusting the action time, the traction bar is immobile and the adjusting rod arranged on the traction bar is moved leftward and rightward to change the distance between the current adjusting screw on the temperature sensing element 14 and the traction bar, so as to change the action time of the delay current.

Description

Mechanism for setting and regulating circuit breaker time-delay current
Technical field
The present invention relates to a kind of low voltage component, be specially a kind of mechanism for setting and regulating circuit breaker time-delay current.
Background technology
Existing circuit breaker is after dispatching from the factory, and the user is regulating delaying current during operate time, and draw bar will change the position, can influence the accuracy that transient current is adjusted like this, reduces the technical performance and the reliability of product.
Summary of the invention
The purpose of this invention is to provide a kind of accurate adjusting circuit breaker time-delay current mechanism of operate time, it is mechanism for setting and regulating circuit breaker time-delay current, the delaying current mechanism for setting and regulating of circuit breaker, comprise pedestal, fixed contact, arc control device, transmission mechanism, lid, handle, knob, draw bar, spring, terminal screw, junction block, adjustment screw and temperature-sensing element, wherein, transmission mechanism is housed on the pedestal, transmission mechanism is provided with the temperature-sensing element of draw bar and band adjustment screw, be provided with extension spring between draw bar and the temperature-sensing element, draw bar rotates and is controlled by spring, it is characterized in that: newly-increased adjusting rod above the draw bar, adjusting rod inserts in the groove at draw bar two ends, cover and be provided with knob, knob is inserted in the adjusting rod boss.
Good effect of the present invention is: because the present invention increases an adjusting rod newly on draw bar, and when knob, adjusting rod move left and right, and draw bar is motionless, having does not influence the adjust advantage of accuracy of transient current.

Fig. 3 is that the user regulates the governor motion schematic diagram of delaying current after operate time.
Fig. 4 is the draw bar schematic diagram.
Fig. 5 is the adjusting rod schematic diagram.
Fig. 6 is the knob schematic diagram.
Fig. 7 is the temperature-sensing element structural representation of band adjustment screw.
Embodiment
As shown in Figure 1, the delaying current mechanism for setting and regulating of circuit breaker, comprise pedestal 1, fixed contact 2, arc control device 3, transmission mechanism 4, lid 5, handle 6, knob 7, draw bar 9, spring 10, terminal screw 11, junction block 12, adjustment screw 13 and temperature-sensing element 14, wherein, transmission mechanism 4 is housed on the pedestal 1, transmission mechanism 4 is provided with the temperature-sensing element 14 of draw bar 9 and band adjustment screw 13, be provided with extension spring 10 between draw bar 9 and the temperature-sensing element 14, draw bar 9 rotates to be controlled by spring 10, it is characterized in that: newly-increased adjusting rod 8 above the draw bar 9, adjusting rod 8 inserts in the groove at draw bar 9 two ends, lid 5 is provided with knob 7, and knob 7 is inserted in adjusting rod 8 boss 15 (sees Fig. 3~Fig. 6).
As shown in Figure 2, knob 7 is not rotated adjusting, and adjusting rod 8 does not move, and draw bar 9 does not also move, and be the operate time that manufacturer sets delaying current operate time at this moment.
As shown in Figure 3, when user's adjusting knob 7 rotates a certain angle, such as 90 degree, knob 7 promotes adjusting rod 8 and is moved to the left, and slides on draw bar 9, and draw bar 9 does not move, at this moment the distance between the screw 13 on adjusting rod 8 and the temperature-sensing element 14 is dwindled, be that distance between adjustment screw and the draw bar is controlled by knob, the product delaying current shortens operate time, and adjusted by the user this operate time.In this adjustment process, because draw bar 9 does not move, guaranteed the accuracy that transient current is adjusted, reach purpose of the present invention.
