Description

Technical Field

[0001] The utility model relates to the technical field of backup protectors, in particular to a backup protector with a remote signaling function. Background Art

[0002] A backup protector is a device that disconnects the fault if the primary protector or circuit breaker fails to operate. When a circuit fault occurs, the circuit's protection immediately sends a signal to disconnect the circuit's disconnecting element (such as a circuit breaker). This immediate protection is the primary protector. If the primary protector fails to operate for various reasons, after a short delay (the delay time varies depending on the circuit requirements), another protector activates and trips the faulty circuit. This protection is the backup protector.

[0003] According to the utility model authorization announcement number "CN213483676U," a backup protector with a remote signaling function is disclosed, comprising a face cover, an upper cover, and a lower cover that fit together. A trip assembly, a drive assembly, a contact assembly, an inlet terminal, and an outlet terminal are respectively disposed within the inner cavity of the upper and lower covers. A remote signaling alarm device is disposed within the cavity of the combined face cover and upper cover. The remote signaling alarm device includes a remote signaling handle, a remote signaling terminal, and a micro switch. The micro switch is connected to the remote signaling terminal via a first wire and controls the on / off of an electrical signal from the remote signaling terminal. The remote signaling handle and the operating handle are combined to work in conjunction and control the on / off of the micro switch. This utility model sets up the remote signaling alarm device separately and isolates it from other components, preventing the occurrence of serious accidents such as failure of the lightning protection system and damage to the monitoring system. It also has the characteristics of small size, large flow rate, low residual pressure, and high safety.

By improving the structure of the handle 2, a space for accommodating the micro switch 3 is formed between the protrusion 21 and the side wall of the base 1, so that the volume of the product does not change, and the overall thickness of the product is less than that of the technical solution in the background technology, and the manufacturing cost is low;

[0023] It is worth mentioning that the base 1 is provided with an end cover 4, and the base 1 is provided with at least two support columns 11, which pass through the micro switch 3, and the support columns 11 provide support for the micro switch 3;

[0024] It is worth mentioning that the first wiring terminal 12 and the second wiring terminal 13 are respectively provided on both sides of the base 1. The signal terminal 5 is provided below the second wiring terminal 13 and is electrically connected to the micro switch 3 through a flexible connecting line 6. The disconnection signal is sent to the background through the signal terminal 5, thereby realizing the remote signaling function of the backup protector;
