Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Such as figure 2 As shown, the air switch that can be connected to the sensor includes main contact 1, free trip mechanism 2, overcurrent release 3, shunt release 4, thermal release 5, undervoltage release 6, stop Button 7, bimetal 8 and heating device 9.

[0025] The heating device 9 is arranged under the bimetal sheet 8, and the heating device 9 may be a heating resistor, or a heating wire or the like. The heating device 9 is connected to the sensor, and when the sensor senses an emergency situation other than the electric circuit and the electrical appliance, it outputs a signal to the heating device 9 . The heating device 9 generates heat rapidly, and the bimetal strip 8 is deformed. Push the free release mechanism to act and cut off the power supply.

[0026] Such as image 3 As shown, the air switch that can be connected to the sensor inclu...

Abstract

The invention discloses an air switch capable of being connected with a sensor, and belongs to the technical field of electrical equipment. The air switch aims to solve the problem that an existing air switch cannot induce sudden emergencies except for a circuit and an electric appliance. The air switch structurally comprises a main contact, a free tripping mechanism, an overcurrent tripping device, a shunt tripping device, a heat tripping device, an undervoltage tripping device, a stopping button and a bimetallic strip, and further comprises a heating device, the heating device is arranged below the bimetallic strip, and the heating device is connected with the sensor. The heating device is a heating resistor or an electric heating wire. The air switch capable of being connected with the sensor comprises the main contact, the free tripping mechanism, the overcurrent tripping device, the shunt tripping device, the heat tripping device, the undervoltage tripping device, the stopping button and the bimetallic strip, and further comprises a sensor tripping device, and the sensor tripping device is a coil, shares one armature with the overcurrent tripping device or the shunt tripping device or the undervoltage tripping device, and is connected with the sensor. The air switch has wide application prospects in the livelihood of people and industry.

Description

technical field [0001] The invention relates to an air switch, in particular to an air switch capable of connecting sensors, and belongs to the technical field of electrical equipment. Background technique [0002] The existing air switch is also a low-voltage circuit breaker, which is used in the circuit to connect, break and carry the rated operating current, and can protect the circuit and the motor in the event of overload, short circuit and undervoltage. Its function is equivalent to the sum of some or all functions of electrical appliances such as knife switch, overcurrent relay, voltage loss relay, thermal relay and leakage protector. It is an important protective electrical appliance in low-voltage distribution network. [0003] Such as figure 1 As shown, the existing automatic air switch includes a main contact 1, a free tripping mechanism 2, an overcurrent tripper 3, a shunt tripper 4, a thermal tripper 5, an undervoltage tripper 6, and a stop button 7 and bimeta...
