Problems solved by technology
Moreover, conventional high-voltage motor control cabinets must place motor control actuators such as C high-voltage vacuum contactors in relatively independent and closed compartments due to safety protection requirements. The traditionally designed high-voltage motor control cabinet structure is only suitable for electrical Transmission control restricts the installation of manual operating mechanism
In addition, the F fuse of the FC control circuit commonly used in the conventional high-voltage motor power distribution cabinet is designed for fixed installation, which is not convenient for the power-off isolation replacement of the fuse core and the safety inspection and maintenance of the C high-voltage vacuum contactor.

Embodiment Construction
[0025] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0026] The specific embodiment of the present invention is like this: as Figure 1-8 As shown, a high-voltage electric fire pump control cabinet with an emergency mechanical pump starting device includes a control cabinet body. The control cabinet body includes a main cabinet 1 and an auxiliary cabinet 2 arranged on one side of the main cabinet 1. The main cabinet 1 is equipped with Control the FC control loop of the fire pump. The FC control loop includes the F fuse handcart 3 connected to the high-voltage power supply line 17 set in the middle of the main cabinet 1 and the C high-voltage vacuum contactor 4 set at the bottom of the main cabinet 1. The C high-voltage The vacuum contactor 4 is provided with an armature ...

The invention discloses a high-voltage electric fire pump control cabinet with an emergency mechanical pump starter. The control cabinet comprises a control cabinet body, the control cabinet body comprises a main cabinet and an auxiliary cabinet arranged in one side of the main cabinet, an FC control loop for control a fire pump is arranged in the main cabinet, and the FC control loop comprises anF fuse cart arranged in the middle portion of the main cabinet and connected with an inlet wire of a high voltage power supply, a C high voltage vacuum contactor arranged in the bottom of the main cabinet, and an emergency manual control mechanism arranged in the bottom of the auxiliary cabinet. The high-voltage electric fire pump control cabinet with the emergency mechanical pump starter is reasonable in design, the emergency manual control mechanism can be used to safely control work of the C high voltage vacuum contactor, use of the high voltage electric fire pump when a secondary controlloop is in failure is ensured, and convenient replacement of the F fuse core and safe maintenance of the C high voltage vacuum contactor are considered in design of the control cabinet.
Description
technical field [0001] The invention relates to the technical field of high-voltage control cabinets, more specifically, it relates to a high-voltage electric fire pump control cabinet with an emergency mechanical pump starting device. Background technique [0002] A highly automated pump start control system is usually configured in the fire protection system, and the C high-pressure vacuum contactor in the control cabinet is a key part of the pump start device. In order to ensure the reliability of the fire protection system, it is required to ensure that the fire pump can be activated manually even when the control circuit fails. Therefore, a mechanical manual operation mechanism is required on the AC contactor. Moreover, conventional high-voltage motor control cabinets must place motor control actuators such as C high-voltage vacuum contactors in relatively independent and closed compartments due to safety protection requirements. The traditionally designed high-voltage ...
