Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
A smoke sensor 9 is mounted above the capacitor 8. In the whole reactive compensation cabinet, the parts with the largest heat productivity are the capacitor 8 and the reactor 7, and the potential safety hazard is also large. The smoke sensor 9 is arranged at the position, so that the working states of the capacitor 8 and the reactor 7 can be monitored, and the monitoring is more targeted. And the smoke sensor 9 is located inside the cabinet 15, but not outside the cabinet 15, in such a way that if smoke is generated inside the cabinet, it can be captured by the smoke sensor 9 for the first time, the alarm hysteresis is reduced.
The cabinet body 15 is provided with a plurality of mounting rails 10, and the smoke sensor 9 is slidably mounted on the mounting rails 10. The user can adjust the specific number and installation position of the smoke sensors 9 according to the specific number of the capacitors 8 and the reactors 7 of the specific reactive compensation cabinet.
Fuse 3 is installed on fuse installation guide rail 17, and fuse 3 passes through the wire to be connected with ac contactor 4, and inlet wire fuse 1 is installed on inlet wire fuse installation guide rail 13, and inlet wire fuse 1 passes through copper tablet 2 and fuse to be connected. The incoming line fuse 1 is electrically connected with the outside to provide integral circuit fusing protection. And fuse 3 is a plurality of, corresponds with condenser 8, and each fuse 3 provides circuit fusing protection for corresponding condenser. The copper plate cover 12 is arranged on the outer side of the copper plate 2, and the copper plate cover 12 provides insulation protection, so that the safety of an operator in the operation process is improved.
The cabinet body 15 is further provided with a contactor mounting guide rail 11, and the alternating current contactor 4 is mounted on the contactor mounting guide rail 11 for a user to operate a circuit. The terminal block 14 is used for adding a node to the circuit, the terminal block 14 is connected with the ac contactor 4 through a lead, and the output end of the capacitor 8 is connected with the ac contactor 4 through a lead.
