Embodiment

[0027] Such as Figure 1 to Figure 4 As shown, a bypass operation vehicle for replacing a distribution transformer 121 without power failure includes a chassis 101 , a low-voltage quick connector 102 , a high-voltage quick input connector 103 and a high-voltage quick output connector 104 . The chassis 101 is provided with a low-voltage switchgear 105, a high-voltage switchgear 106, a dry-type transformer 107, and a cable pay-off device 113. The cable pay-off device 113 includes a skeleton 113a and two groups of cable reels 113b distributed up and down. 113b is used to store three 20-meter-long high-voltage power-taking flexible cables 117 and eight 20-meter-long low-voltage power transmission cables 118 .

[0028] The low-voltage quick connector 102 is connected to the low-voltage switchgear 105 through a first low-voltage cable 108, and the low-voltage switchgear 105 is connected to the dry-type transformer 107 through a second low-voltage cable 109, and the dry-type transfor...

Abstract

The invention discloses a bypass operation vehicle capable of enabling users to change a distribution transformer without power cutting. The bypass operation vehicle comprises a chassis, a low tension fast connector, a high tension fast input connector and a high tension fast output connector. A low tension switch cubicle, a high tension switch cubicle and a transformer are arranged on the chassis, the low tension fast connector is connected with the low tension switch cubicle through a first low tension cable, the low tension switch cubicle is connected with the transformer through a second low tension cable, the transformer is connected with the high tension switch cubicle through a first high tension flexible cable, and the high tension switch cubicle is respectively connected with the high tension fast input connector and the high tension fast output connector through a second high tension flexible cable and a third high tension flexible cable. A transportation frame is added, the bypass operation vehicle can be conveniently and flexibly scheduled, cross-region first-aid repair work can be achieved, and the bypass operation vehicle has strong adaptability and high application capability.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for replacing distribution transformers, in particular to a bypass operation vehicle for replacing distribution transformers without power failure. Background technique [0002] In recent years, the 10kV distribution network system has developed rapidly, but distribution transformers often need to be replaced during the operation of the distribution network due to overhaul, technical transformation, overload, external force damage and other reasons. In the current technology, the replacement of distribution transformers requires a power outage in a certain area, and the replacement of distribution transformers after power failure will affect people's life and production electricity consumption on this line. Contents of the invention [0003] Based on this, in view of the above problems, it is necessary to propose a bypass operation vehicle for replacing distribution transformers without power ...
