Problems solved by technology

[0003] The traditional surge protector indicates the operation of the surge protector and the thermal release through two independent mechanisms. Abnormalities caused by problems with accessories, and when the surge protector triggers a thermal trip alarm, it is necessary to actually check whether the thermal tripper performs a trip operation, or the false alarm is caused by the improper assembly of the surge protector body and the base , resulting in a larger workload when troubleshooting

Embodiment 1

[0028] Such as figure 1 and figure 2 As shown, a plugging judgment method includes the following steps:

[0029] S1 plug-in monitoring: monitor the cooperation between the first connector 6 provided on the body 4 of the surge protector and the second connector 8 provided on the base 10;

[0030] S2 thermal trip monitoring: monitor the cooperation of the third connector 5 provided on the surge protector body 4 with the fourth connector 7 provided on the base 10;

[0031] S3 Judgment of cooperation between the surge protector body 4 and the base 10: if the first connector 6 is matched with the second connector 8, then the surge protector body 4 is matched with the base 10; if the first connector 6 is matched with the second connector 8 If the two connectors 8 are not mated, then the surge protector body 4 and the base 10 are not mated;

[0032] S4 thermal trip state judgment: if the first connector 6 is mated with the second connector 8, and the third connector 5 is mated wi...

Embodiment 2

[0036] Such as figure 2 As shown, the surge protector provided by the present invention includes a first connector 6, a second connector 8, a third connector 5 and a fourth connector 7; the first connector 6 and the surge The protector body 4 is connected, and the second socket 8 is arranged on the base 10; when the surge protector body 4 is matched with the base 10, the first socket 6 can cooperate with the second socket 8; the third socket The connector 5 cooperates with the thermal release 1 of the surge protector body 4, and when the surge protector cooperates with the base 10, the third socket 5 can be connected with the fourth socket under the action of the thermal release 1. Fitting 7 fits.

[0037] The first connector 6 is provided with a temperature sensor, the temperature measuring end of the temperature sensor is used to monitor the temperature of the piezoresistor 2, and the data transmission end of the temperature sensor realizes electrical connection through th...

Abstract

The invention relates to the field of electrical equipment, in particular to a plugging judgment method and a surge protector. The plugging judgment method provided by the invention comprises the following steps: plugging monitoring: monitoring matching of a first plug connector arranged on a surge protector body and a second plug connector arranged on a base; thermal tripping monitoring: monitoring matching of a third plug connector arranged on the surge protector body and a fourth plug connector arranged on the base; the surge protector body and the base are matched for judgment; and judging a thermal tripping state. Surge protector abnormity caused by various conditions can be judged, and the surge protector triggers thermal tripping alarm, so that the workload during troubleshooting is reduced.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a plug-in judging method and a surge protector. Background technique [0002] The function of the thermal release is to protect the circuit. When the surge protector is subjected to a continuous small current due to the deterioration of the varistor, it will disconnect the circuit in a timely and reliable manner. When the thermal release is subjected to a continuous small current, the thermal The hot-melt structure of the trip unit melts under the action of electric current, thereby blocking the connection of the circuit. The position of the ejector rod between the existing surge protector body and the base realizes the thermal tripping alarm. Specifically, a metal sheet is connected to the connecting solder piece of the piezoresistor through a hot-melt structure, and the ejector rod plays the role of the elastic member. The bottom abuts against the metal sheet, and the belt ...
