Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment and power distribution systems, in particular to a load switch cabinet with a power-off indication function. Background Art

[0002] A load switch cabinet is a collection of equipment used to control and protect load current and related circuits in a power system. It is mainly composed of load switches, fuses (or protection relays), control power supplies, current transformers, voltage transformers, lightning arresters and other components, and is integrated into one or more metal cabinets (1). These components work together to achieve the control, monitoring and protection functions of the load current in the power system. At present, during the use of the load switch cabinet, when it triggers the current overload protection, that is, when the fuse is disconnected, it is difficult for people to find the cause of the power outage because the switch cabinet does not have an indication function. It takes a lot of time to eliminate it, which wastes a lot of time.

[0003] Therefore, it is necessary to design a load switch cabinet with power-off indication function to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems of the shortcomings of the prior art and to provide a load switch cabinet with a power-off indication function.

[0005] The technical solution of the utility model is: a load switch cabinet with a power-off indication function, comprising a cabinet body and a fuse assembly arranged in the cabinet body; the incoming line end of the fuse assembly is electrically connected to the power supply, and the outgoing line end is electrically connected to the electrical equipment; an indicating mechanism is provided on one side of the incoming line end of the fuse assembly; the indicating mechanism includes an indicator sign; an observation window is provided on one side of the cabinet body corresponding to the indicator sign; when the fuse assembly does not fail, the indicator sign cannot be observed in the observation window, and when the fuse assembly fails, the internal striker of the fuse drives the indicating mechanism to operate so that the indicator sign faces the observation window.

[0006] The fuse assembly includes a plurality of striker-type fuses arranged in sequence from top to bottom; both ends of each striker-type fuse are arranged obliquely in the cabinet through a fixing bracket.

[0007] The indicating mechanism also includes a rotating shaft arranged in the cabinet body and rotating in a vertical direction; the indicating plate is fixed to the rotating shaft through a connecting bracket; a connecting block corresponding to each striker-type fuse is provided on the rotating shaft; an excitation rod is provided between the connecting block and the corresponding striker-type fuse; one end of the excitation rod is hinged to the connecting block, and the other end is located at the incoming line end of the corresponding striker-type fuse.

[0008] A fixing plate is provided in the cabinet; a through hole is provided on the fixing plate and corresponds to the excitation rod one by one; the excitation rod is passed through the through hole; and an excitation disk is provided at one end of the excitation rod corresponding to the striker fuse.

[0009] A paddle is provided on the top of the rotating shaft; a micro switch is provided below the paddle; the micro switch is used to control the on and off of the load switch cabinet and the external circuit; when the paddle rotates, it contacts the contact of the micro switch, triggering the micro switch.

[0010] The bottom of the cabinet is provided with rollers.

[0011] By adopting the above technical solution, the utility model has the following beneficial effects: the utility model is provided with an indicator mechanism. When the fuse assembly has not failed, the indicator sign cannot be observed in the observation window. When the fuse assembly fails, the internal striker of the fuse drives the indicator mechanism to operate, so that the indicator sign is facing the observation window, thereby making it easy for people to observe the indicator sign and know that the fuse assembly has failed, so that people can quickly find the cause of the power outage, avoiding wasting time in searching for the fault source without knowing it due to a fault in the load switch cabinet.

[0017] (Example 1)

[0018] See Figure 1 and Figure 2A load switch cabinet with a power-off indication function in this embodiment includes a cabinet body 1 and a fuse assembly 2 arranged in the cabinet body 1; the incoming end of the fuse assembly 2 is electrically connected to the power supply, and the outgoing end is electrically connected to the electrical equipment; an indicating mechanism 3 is provided on one side of the incoming end of the fuse assembly 2; the indicating mechanism 3 includes an indicator sign 3-1; an observation window is provided on one side of the cabinet body 1 corresponding to the indicator sign 3-1; when the fuse assembly 2 is not faulty, the indicator sign 3-1 cannot be observed in the observation window. When the fuse assembly 2 fails, the internal striker of the fuse drives the indicating mechanism 3 to operate so that the indicator sign 3-1 faces the observation window.

[0019] Furthermore, the fuse assembly 2 includes a plurality of striker-type fuses arranged in sequence from top to bottom; both ends of each striker-type fuse are tilted and arranged in the cabinet 1 through a fixed bracket. In this embodiment, a plurality of striker-type fuses are provided. When any striker-type fuse fails, the indicating mechanism 3 can be driven to operate, thereby ensuring the accuracy of the indication.
