Description

Technical Field

[0001] The utility model relates to the field of grounding trolleys, in particular to a KYN28 cabinet simple grounding trolley. Background Art

[0002] With the development of economic construction, the demand for electricity is getting higher and higher. Due to the limitation of the number and energy of operation and maintenance personnel, the demand for the promotion and construction of intelligent unmanned distribution stations is also increasing, which in turn promotes the in-depth research of various panel factories in the field of intelligent control technology.

[0003] KYN28 is an armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear). It is a three-phase AC 50Hz indoor complete power distribution device used to receive and distribute network power and implement control, protection and monitoring of circuits. This switchgear has the functions of preventing misoperation of circuit breakers, preventing the push and pull of trolleys with load, preventing the closing of grounding switches with power on, preventing the grounding switches from transmitting power in the grounding position and preventing the mistaken entry into the live interval, which is referred to as the "five protections". It can be equipped with VDS or VS1 vacuum circuit breakers, and can also be equipped with imported VM1 and VD4 vacuum circuit breakers. This device is mainly used for power plants, power transmission of small and medium-sized generator sets, power distribution of industrial and mining enterprises and institutions, and power transformation, power transmission and starting of large high-voltage motors in secondary substations of power systems for control, protection and monitoring.

[0004] For example, a Chinese patent with publication number CN212876311U discloses a new KYN28 cabinet, including a KYN28 cabinet body and an installation cover, a temperature display is fixedly installed on the front left upper surface of a movable door close to the front upper surface of the KYN28 cabinet body, a temperature sensor is fixedly installed on the upper surface of the inner left wall of the KYN28 cabinet body, and a uniform heat dissipation fan is fixedly installed at the center of the inner left wall of the KYN28 cabinet body. The utility model uses the temperature sensor, the uniform heat dissipation fan and the temperature display to sense the temperature inside the KYN28 cabinet body through the temperature sensor to electrically start the cooling water pump, the drive motor and the uniform heat dissipation fan, and the uniform heat dissipation fan makes the airflow inside the KYN28 cabinet body evenly distributed inside the KYN28 cabinet body through the uniform heat dissipation fan, so that the data sensed by the temperature sensor is more accurate, and the airflow temperature information contacted by the temperature sensor is displayed through the temperature display, which is convenient for the staff to view, so that when the equipment is used, the temperature measurement can be more accurate and convenient to view.

[0005] In summary, the existing grounding trolleys for KYN28 cabinets still have many disadvantages, which are summarized as follows:

[0006] ① The existing grounding trolleys for KYN28 cabinets are all integral structures with non-spliced ​​frames, which have high production costs;

[0007] ② When the grounding position changes, the existing matching trolley cannot adapt and the operation is more complicated. Utility Model Content
