Miniaturized mobile box-type substation

Abstract

The invention discloses a miniaturized mobile box-type substation, and belongs to the technical field of electrical equipment. The substation comprises a closed handcart chamber, a vacuum load switch-fuse combined electric appliance handcart, a dry-type transformer, a metering chamber, a circuit breaker chamber, a transformer chamber, a cable outlet chamber, an upper wire inlet chamber, a lower wire inlet chamber, an all-insulation and all-shielding plug, a meter gauge, a frame circuit breaker, a molded case circuit breaker, a capacitor chamber, an intelligent integrated capacitor and an emergency power plug. The invention provides the miniaturized substation which adapts to more working environments, shortens on-site power failure time, combines a vacuum arc-extinguishing chamber and a current-limiting fuse together, and changes the characteristics that the high-voltage side of a box-type substation adopts a switch cabinet form and the low-voltage side adopts dual power supply reliability. The emergency power plug matched with a generator car is configured; and the electrical load can be directly supplied with power by the transformer of the equipment, the reliable operation of the on-site electrical load is ensured by dual power supply, and precious time is won for troubleshooting and emergency repair of electric power personnel.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to a miniaturized mobile box-type substation. Background technique [0002] In the current field of electrical equipment technology, the application of box-type substations is becoming more and more extensive, but the occurrence rate of electrical failures in box-type substations is also becoming more frequent. When a fault occurs, due to the large and heavy box-type substation itself, it is very inconvenient to transport and replace, and it often takes a certain amount of time for electricians to go through investigation and repair, which causes a certain area of ​​power outages, especially in some key areas. For example, in hospitals, banks, industrial and mining enterprises, including in residential areas, long-term power outages not only affect people's daily life, but more seriously may involve economic property losses and even people's lives.

[0002] In the current field of electrical equipment technology, the application of box-type substations is becoming more and more extensive, but the occurrence rate of electrical failures in box-type substations is also becoming more frequent.

When a fault occurs, due to the large and heavy box-type substation itself, it is very inconvenient to transport and replace, and it often takes a certain amount of time for electricians to go through investigation and repair, which causes a certain area of ​​power outages, especially in some key areas. For example, in hospitals, banks, industrial and mining enterprises, including in residential areas, long-term power outages not only affect people's daily life, but more seriously may involve economic property losses and even people's lives.
