Description
[ technical field ] A method for producing a semiconductor device
The invention relates to an overvoltage protector for remotely transmitting alarm information, and belongs to the technical field of overvoltage protectors.
[ background of the invention ]
As an overvoltage protector is a device for providing safety protection for electronic equipment or lines, it is generally used to limit overvoltage, and when overvoltage occurs, it can perform functions of shunting and limiting voltage, so as to prevent damage to equipment or lines. Most of the overvoltage protection elements adopt overvoltage protection elements as voltage limiting elements, and the overvoltage protection elements have very large resistance in a normal state, which is equivalent to a disconnection state, so that the conduction of a protected line is not influenced; when the voltage in the circuit exceeds the warning value, if the conditions such as lightning strike occur, the overvoltage protection element can make a corresponding response within nanosecond-level time, the resistance value of the overvoltage protection element is rapidly reduced, and at the moment, the overvoltage protection element is equivalent to a conduction state, shunts the voltage and prevents the overvoltage from damaging the electric circuit. However, the overvoltage protection element is aged and deteriorated after voltage is shunted for many times, and at this time, the overvoltage protection element is easy to heat up, in order to prevent fire caused by continuous heating up of the overvoltage protection element, a safety mechanism is generally connected in series with the overvoltage protection element, the safety mechanism is connected with the overvoltage protection element by low-temperature soldering, when the overvoltage protection element is heated up, the connection part is melted, and the overvoltage protection element is disconnected from the circuit under the action of elastic force in the safety mechanism, so that the continuous heating up of the overvoltage protection element is avoided. An electrical circuit generally using an overvoltage protector is a three-phase circuit.
The existing overvoltage protector generally integrates components to form a three-phase combined overvoltage protector, and has the following problems: 1. at least three overvoltage protection elements are arranged inside the overvoltage protection device, so that in order to avoid mutual influence of heating of the overvoltage protection elements, the distance between the adjacent overvoltage protection elements is designed to be larger, and the volume of the whole overvoltage protection device is larger; 2. each overvoltage protection element is required to be provided with an independent corresponding safety mechanism, and a plurality of safety mechanisms can possibly generate mutual influence when acting, so that enough space is required between adjacent safety mechanisms; 3. in order to send out early warning information in time, a microswitch and a remote signaling terminal are independently arranged for each safety mechanism, so that the space is occupied, and the cost is high. In summary, the conventional overvoltage protector has a large volume due to the structural design, and is difficult to satisfy the trend of miniaturization of equipment. In addition, although part of the overvoltage protectors have a remote signaling early warning function, a certain time still exists between the time when the workers receive the early warning information and the time when the overvoltage protectors are replaced, and protected equipment or circuits are in an unprotected state in the time, so that potential safety hazards exist.
