Problems solved by technology

[0003]At present, the maintenance of power grid equipment is mostly manual, the sequence of power grid maintenance steps is complicated, the risk of error is high, and the aging speed of power grid maintenance professionals is increasing, and the growth of new employees The development of power grids and training cannot keep up with the speed of power grid development, which greatly increases potential operational risks. In particular, it is inevitable that operators may misoperate switches that do not need to be operated, resulting in safety accidents and threatening the personal safety of operators.

Embodiment 1

[0043] figure 1 It is a flow chart of a maintenance method for a power distribution room provided in Embodiment 1 of the present invention. The maintenance method for a power distribution room includes:

[0044] S10: Obtain the status and number of the power outage range and the final switch to be operated;

[0045] Obtain the work site where the maintenance operation is required, the work site where the maintenance operation is required is the range where the power outage is required, and the upper-level switch of the work site where the maintenance operation is required is the switch that needs to be operated. The state of the switch includes the closed state of the switch and the open state of the switch. After checking the state of the switch obtained manually and the state of the switch obtained by the system, the final state of the switch to be operated is obtained. Each switch corresponds to a unique serial number, and after obtaining the serial number of the switch, i...

Embodiment 2

[0055] figure 2 It is a flow chart of a maintenance method for a power distribution room provided in Embodiment 2 of the present invention, refer to figure 2 , optionally, the maintenance methods for the power distribution room include:

[0056] S11: Obtain the power outage range;

[0057] S12: Obtain the state and number of the switch to be operated input by the user;

[0058] The user refers to the operator. After the operator conducts the on-site survey, he inputs the state and number of the switch to be operated into the power system to generate a work ticket, and the power system obtains the state and number of the switch to be operated according to the work ticket.

[0059] S13: Obtain the state and number of the switch to be operated collected by the switch lock;

[0060] The switch lock is connected with the geographic information system (GIS system), and each switch lock corresponds to a sub-switch. The GIS system obtains the status and number of the switch to be...

Embodiment 3

[0075] image 3 For the flow chart of a method for overhauling a power distribution room provided in Embodiment 3 of the present invention, refer to image 3 , optionally, the maintenance methods for the power distribution room include:

[0076] S10: Obtain the status and number of the power outage range and the final switch to be operated;

[0077] S20: Generate a second operation ticket while generating the first operation ticket according to the state and number of the switch to be operated finally and the operation ticket template;

[0078] Optionally, the operation ticket template includes at least: a transfer operation template and a transfer maintenance template.

[0079] The first operation ticket corresponds to the operation ticket in the maintenance state, and needs to be generated according to the transfer to maintenance template. The transfer to maintenance template stipulates that the first switch is off, the second switch is off, and the third switch is on. Af...

Abstract

The invention discloses a maintenance method and device for a power distribution room. The maintenance method for the power distribution room comprises the steps of: acquiring a power failure range and a state and a serial number of a switch needing to be operated finally; generating a first operation order according to the state and the serial number of the switch which finally needs to be operated and the operation order template; and sending first control instructions to different switch locks one by one according to an operation sequence of the first operation order, so that the switch locks control the corresponding switch to act according to the first control instructions. The switch of the power distribution room comprises a plurality of sub-switches, during maintenance, the sub-switches must follow a specific operation sequence to act, the switch locks enable the corresponding sub-switches to be turned on after receiving instructions, and an operator can perform next operation on the sub-switches. According to the maintenance method and the device of the invention, different switch lock actions are controlled one by one according to the operation sequence of the operation order, so that an operator completes the operation of the switch, equipment maintenance is carried out, misoperation of the switch can be avoided, and the personal safety is ensured.

Description

technical field [0001] Embodiments of the present invention relate to power grid maintenance technology, in particular to a maintenance method and device for a power distribution room. Background technique [0002] With the growth of power demand and the speed of grid construction, the demand for electricity consumption in society is gradually increasing, and the frequency of maintenance of grid equipment is also increasing. [0003] At present, the maintenance of power grid equipment is mostly manual. The order of power grid maintenance steps is complex, and the risk of error is high. Moreover, the aging speed of power grid maintenance professionals is increasing. The growth and training of new employees cannot keep up with the development speed of the power grid, which greatly increases the potential. Operational risks, especially unavoidable operators may misoperate switches that do not need to be operated, resulting in safety accidents and threatening the personal safety...
