High voltage solid insulation looped network switch equipment

Abstract

The invention discloses high voltage solid insulation looped network switch equipment. The equipment comprises a base, a bus chamber, a breaker chamber and a cabinet body, wherein the cabinet body ismounted at the top of the base; an upper door body is mounted at the top of one side of the cabinet body; a name plate is arranged on the upper door body; a lower door body is mounted at the bottom ofone side of the cabinet body; a control panel is mounted at the top of one side of the lower door body; a dummy bus is mounted at the center of one side of the lower door body; a current detector ismounted at the top of one side of the cabinet body; a current transformer is mounted at one end inside the breaker chamber below a supporting insulator; a cable is mounted at the center of the bottomof the interior of the breaker chamber. As a epoxy resin insulating shaft is provided to serve as an insulating medium, and rubber gaskets are arranged in positions where the upper door body and the lower door body are connected with the cabinet body, the equipment cannot produce hazardous substance, and is small in environmental pollution, and beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a high-voltage solid insulation ring network switchgear. Background technique [0002] High-voltage ring network switchgear is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size and low price. , can improve power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises, but the current high-voltage ring network Switchgear generally adopts SF6 insulation. Although it can complete the arc extinguishing and insulation performance to a certain extent, due to the combination of SF6 with water, or under th...

[0002] High-voltage ring network switchgear is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size and low price. , can improve power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises, but the current high-voltage ring network Switchgear generally adopts SF6 insulation. Although it can complete the arc extinguishing and insulation performance to a certain extent, due to the combination of SF6 with water, or under the action of high-power arc, spark discharge and corona discharge, it will decompose substances that are toxic to the human body, and SF6 is also highly polluting to the environment. At the same time, the existing such devices have complex structures, poor overall sealing, low safety in use, inconvenient maintenance and repairs, and no moisture-proof devices, making the high-voltage cabinet itself easy to use. Moisture will easily lead to short circuit of parts in the cabinet and cause failure, which is not conducive to the use of the device. At the same time, the traditional device of this type does not have a fan, which makes it difficult to dissipate the heat in the high-voltage cabinet, which will easily cause damage to the device and shorten the length of the device. In addition, this type of device is not equipped with an anti-leakage device, so that it cannot be found in time when the leakage occurs in the cabinet, which will easily lead to accidents and pose a certain threat to the safety of the staff. Therefore, there is an urgent need for a high-voltage solid Insulated ring network switchgear to meet people's needs
