Protector for low-voltage electric appliance

Abstract

The invention discloses a protector for a low-voltage electric appliance. The protector comprises a protector shell, the top of the protector shell is fixedly connected with a conductive wire; the inner wall of the protector shell is fixedly connected with a fixed arm; the conductive wire is fixedly connected to the top of the fixed arm, a first wire is fixedly connected to the interior of the fixed arm, a contact plate is fixedly connected to the top of the inner wall of the fixed arm, a first contact is fixedly connected to the inner wall of the fixed arm, and a second contact is movably attached to the surface of the first contact. When a circuit is in a high-voltage state, a heating block generates heat and enables the movable arm to rotate quickly; the first contact and the second contact are separated, a third contact makes contact with the contact plate, the flowing path of current is changed, voltage reduction processing is conducted on high-voltage current through a high-resistance resistor, circulation of the current in a circuit is maintained, a low-voltage electric appliance is prevented from being broken down by high voltage, and therefore the purpose of protecting thelow-voltage electric appliance is achieved.

Description

technical field [0001] The invention relates to the field of low-voltage protectors, in particular to a protector for low-voltage electrical appliances. Background technique [0002] Today, the development of human science and technology has entered a stage of highly informatized development, but it is still plagued by three factors: energy, environment and safety, especially environment and safety. Safety is the basic condition for maintaining people's normal life and work. There are many factors that cause insecurity, but they fall into two categories: natural disasters and man-made disasters. Without considering the human factors, since ancient times, we human beings have always carried out tenacious resistance to natural disasters with the spirit of active exploration, especially the protection against lightning. In the ten years of international natural disaster mitigation determined by the United Nations, lightning disasters have risen to the top of the list of natura...

Problems solved by technology

[0003] However, when the existing technology is actually used, it can still effectively protect the slow temperature rise process. In the case of rapid temperature rise, the low-voltage protection device cannot sense this process in time and does not take action, resulting in low-voltage electrical appliances being broken down by high voltage, and it is impossible to realize low-voltage protection. electrical protection
