Embodiment 1

[0050] refer to Figure 1-Figure 9 , the UHV DC phase condenser station multifunctional operation and maintenance work vehicle provided in this embodiment includes a flatbed truck 1 and a trolley 2 .

[0051] The trolley 2 is used to carry cylinders such as image 3 as shown, image 3 The direction shown by the middle arrow is the advancing direction of the handcart 2 (head direction). The bottom of the cart 2 is provided with two wheels 21, and the bottom of the tail is provided with two support rods 22; in order to prevent the gas cylinder from rolling in the handling project, the top of the cart 2 is provided with an arc-shaped supporting plate 23, and the cart of the cart 2 One end of the tail is vertically fixedly provided with a gas cylinder baffle 24 , and the central axis of the arc supporting plate 23 is perpendicular to the gas cylinder baffle 24 . When the trolley 2 was placed on a horizontal plane, the rear of the cart was higher than the front of the cart, whic...

Embodiment 2

[0070] refer to Figure 10-Figure 12 Compared with Embodiment 1, the multi-functional operation and maintenance operation vehicle of the UHV DC camera station provided by this embodiment has been improved as follows: the flatbed truck 1 is also provided with a locking mechanism 18, which can automatically lock the wheelbarrow 2 The support rod 22 is locked in the support groove 141 .

[0071] Such as Figure 10 As shown, the locking mechanism 18 includes a lock tongue 181 , a lock tongue chamber 182 , a pull rod 183 , a spring 185 , a fixing block 184 and a pull ring 187 . The deadbolt bin 182 is arranged horizontally and is vertically fixedly connected with the supporting groove 141. The dead bolt 181 is arranged in the deadbolt bin 182. The specification of the deadbolt bin 182 matches that of the deadbolt 181. The inner horizontal movement, but unable to rotate; the spring 185 is arranged inside the deadbolt chamber 182, and the deadbolt 181 can be inserted into the insid...

Embodiment 3

[0076] refer to Figure 13-Figure 14 Compared with Embodiment 2, the multi-functional operation and maintenance operation vehicle of the UHV DC phase adjustment station provided in this embodiment has been improved as follows: the splint 153 is connected to the slider 152 in rotation, and the platform 14 is hollowed out for the rotation of the splint 153. A card slot 143 for horizontal movement.

[0077] The splint 153 of this embodiment can be rotated into the lower part of the platform 14 when it is not in use, so that there are no protrusions on the platform 14 and more items can be placed.

Abstract

The invention provides a multifunctional operation and maintenance operation vehicle for an extra-high-voltage direct-current phase modifier station, and belongs to the technical field of electric power operation and maintenance. The vehicle comprises a flat car and a trolley. Wheels are arranged on the lower portion of a trolley head of the trolley, a supporting rod is arranged on the lower portion of a trolley tail, an arc-shaped supporting plate is arranged on the top, a gas cylinder baffle is vertically and fixedly arranged at the trolley tail end, and the central axis of the arc-shaped supporting plate is perpendicular to the gas cylinder baffle. The flat car is an electric four-wheeler, a platform of the flat car is provided with wheel pits used for containing wheels of the trolley and supporting grooves used for containing supporting rods of the trolley, and the wheel pits and the supporting grooves are sunken downwards. The tail of the flat car is provided with a control handle for control and a pedal for an operator to stand, and the head of the flat car is provided with a tail plate for the trolley to go up and down. The transportation problem of auxiliary service equipment and facilities of the phase modifier station can be solved, the transportation difficulty can be effectively reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power operation and maintenance, and in particular relates to a multi-functional operation and maintenance operation vehicle of an ultra-high voltage direct current (UHV) DC phase-conditioning station. Background technique [0002] In the sequence of power grid construction in my country, the UHVDC grid has the characteristics of long transmission distance, large transmission capacity, and low loss. It is an important carrier for the realization of clean energy cross-region transmission. In the high-voltage AC-DC hybrid power grid, there are problems such as weak power grid at the sending end of DC transmission and insufficient reactive power of the power grid at the receiving end, which affects the safe and stable operation of the power grid. In the power grid system, condensers are often used to solve the above problems. The condenser station is the station with the condenser unit installed. The...
