Embodiment Construction

[0014] The specific scheme of the embodiment is as follows:

[0015] as attached figure 1 As shown, the present invention adopts the following measures to realize: the relay (1) is composed of the control unit (2) and the protection unit (3), the relay (1) and the surge protection device (5), the detection device (6), the measurement and control device (4) and the like are installed together in the casing (9) of the surge protector (10) to become a surge protector product. In the specific work, the surge protection line enters the protection unit (3) of the relay (1) from the surge input terminal (7), the protection unit (3) is represented as a contact in this embodiment, and the output of the protection unit (3) enters The surge protection device (5) is output from the surge output terminal (8) to complete the surge protection function. When the surge protection device (5) is short-circuited or deteriorated, the detection device (6) transmits information to the measurement ...

Abstract

The invention relates to a novel back-up protection device for a surge protector. The back-up protection device adopts a relay (1), wherein a control unit (2) and a protection unit (3) are arranged in the relay (1); the control unit (2) is connected with an external measurement and control device; and the protection unit (3) is connected in series with a surge protection device (5) in a surge protection return circuit. The device adopts a contact device or a contact capable of bearing strong surge currents as the protection unit (3), can prevent the surge protector from being damaged when the surge protector discharges the surge currents, and adopts the control unit (2) connected with the measurement and control device to realize controllable operation of back-up protection of the surge protector. Even if the surge protector has weak abnormal information, the back-up protection device can disconnect the protection unit (3) through the control unit, separates the surge protector from circuits and effectively solves the existing problems.

Description

technical field [0001] The invention relates to a novel backup protection device of a surge protector, which belongs to the technical field of surge protection of electronic and electrical equipment. technical background [0002] Lightning and line surges caused by lightning and line surges caused by other reasons are important reasons for the aging and damage of electrical and electronic equipment. It is one of the important measures for lightning protection to install surge protectors on metal lines such as power lines, signal lines and control lines connected to electronic equipment. In this technical field, an important problem currently exists is: while the surge protector protects the equipment, its own devices will gradually deteriorate until completely damaged, or directly damaged under excessive surge impact, or cause Switch-type surge protection devices generate freewheeling; for power surge protectors, the damage or damage caused by them includes short-circuit (i...
