Embodiment

[0023] like figure 1 , figure 2 , image 3 as well as Figure 4 In the shown embodiment, a prefabricated box-type temporary substation that can be used in an emergency, the box body 1 is provided with waterproof sockets for connecting with external cables, and the box body 1 is equipped with high-voltage switchgear, distribution transformers and low-voltage substations. In the power distribution device, the box body 1 is also provided with a rewinding sheave 2 for cable retraction, a reciprocating screw 7 connected in rotation with the box body 1, and a lead block 6 matched with the reciprocating screw 7, on which the reciprocating screw 7 A first helical groove 19 and a second helical groove are provided. The helical directions of the two helical grooves are opposite. The first helical groove 19 and the two ends of the second helical groove are smoothly connected. One end is set with a synchronous wheel for driving the reciprocating lead screw 7 to rotate, the synchronous...

Abstract

The invention discloses a prefabricated box-type temporary substation that can be used in an emergency, which includes a box for providing support, sockets on the box, high-voltage switchgear in the box, a distribution transformer and a low-voltage power distribution device. A rewinding sheave, a reciprocating lead screw and a wire block matched with the reciprocating lead screw are used for cable retraction in the box. The present invention utilizes the frictional force to cause the friction block to slide relative to the pin body, thereby triggering the oil outlet from the oil storage chamber, and the lubricating oil enters the spiral groove from the oil outlet to lubricate the sliding of the pin body, reducing the need for operation Or on time to replenish the lubricating oil program dependence.

Description

technical field [0001] The invention relates to a substation, in particular to a prefabricated box-type temporary substation which can be used in an emergency. Background technique [0002] Prefabricated box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme, which is about transformer step-down, low-voltage power distribution, etc. The functions are combined together and installed in a movable steel structure box. Considering that there is a pull-out cable and the cable inlet needs to be wound, a cable arrangement device is installed in the box, and the cable arrangement device can cooperate with the winding The wire device guides the winding position of the cable so that the cable is evenly wound on the winding device. For example, an "automatic cable arrangement device" di...
