1) the primary equipment is powered off, protected and checked, and the primary equipment is called a type of maintenance task;
2) the method comprises the following steps that primary equipment is powered off, and protection and bus protection failure loop tests are called as second-class maintenance tasks;
3) one-time equipment is not powered off, and the defect elimination treatment is protected, which is called three types of maintenance tasks;
4) the primary equipment is not powered off, and a transmission test is carried out after the defect is eliminated, which is called four types of maintenance tasks;

rule 1: primary equipment cannot operate without protection:
inference 1: protecting the single configuration scheme, and protecting equipment which must be decommissioned for one time during maintenance;
and (3) inference 2: protection is duplicated, i.e. one set of protection is taken out of operation (including a signal-on-state), and the other set of protection must be taken out of service for one-time equipment during maintenance.
Rule 2: the maintenance equipment can not influence the safety of the operation equipment:
inference 1: after an IED object of a maintenance task is determined, safety measure isolation operation is firstly carried out on running equipment, and then maintenance equipment operation is carried out;
and (3) inference 2: the safety measure isolation operation should be conducted one by one with each IED device as an object, and the safety measure isolation cannot be conducted in a crossed mode.
Rule 3: in the stopping and re-service operation process of the protection equipment, the maintenance pressing plate can not exit when the protection system is not in a normal state, and the normal state refers to that all alternating current inputs (bus differential, multiple transformer intervals) and control signal inputs/outputs of the protection system are normal:
inference 1: protection out-of-service operation, namely disconnecting a transmission/reception (input/output) soft pressing plate at an operation interval; disconnecting the maintenance interval sending/receiving (input/output) soft pressing plate; thirdly, disconnecting a tripping and closing hard pressure plate; fourthly, putting in a maintenance pressing plate; short-circuit the corresponding CT terminal and disconnect the corresponding PT terminal;
and (3) inference 2: protection and restoration: restoring corresponding CT terminals and PT terminals; putting into maintenance interval sending/receiving (input/output) soft pressing plate; putting into operation interval sending/receiving (input/output) soft pressing plate; fourthly, putting a tripping and closing hard pressing plate; quitting the maintenance pressing plate;
rule 4: unnecessary maintenance operation is reduced as far as possible:
inference 1: the signal loop sent by the maintenance equipment to the operation equipment must be isolated, and the signal loop sent by the operation equipment to the maintenance equipment can be isolated; (Note: whether this principle applies or not can be determined by the user himself).
The device rule means: based on the relevant rules that the device principle features need to follow:
rule 1: double bus busbar differential protection rules:
when primary equipment is powered off and a line (transformer) is protected and overhauled, an isolation disconnecting link of a corresponding interval (the overhauled line/transformer) of bus protection needs to be put into the line to forcibly divide a soft pressing plate;
description of the drawings: the running bus differential protection device needs to know the position of an actually running isolation switch so as to prevent errors in the differential flow calculation of the segmented bus protected by the bus; when the intelligent terminal of the overhaul interval quits operation, the position signal of the isolation disconnecting link of the receiving bus in the GOOSE loop needs to be forcibly set so as to avoid the overhaul interval participating in mother difference calculation.
Rule 2: a half-wired line protection rule:
the primary equipment is out of service, before the intelligent terminal is operated to overhaul the pressing plate, the related circuit protection (edge and middle) circuit breaker is placed in overhaul' the pressing plate is put into use (if any); when the line protection 'breaker X' overhauls the soft clamp plate and puts 1, it indicates that the trip position that the protection device fixed approved 'breaker X' is 1, and the protection device can not approve the GOOSE opening information of 'breaker X' split-phase trip position this moment. This function generally is used for the condition that circuit breaker X intelligent terminal overhauld, and the effect is equal to circuit breaker X on the protection screen cabinet of conventional station overhauls and switches the handle.
Rule 3: the pilot line protection device rule is as follows:
when the line is protected and overhauled, the optical fiber channel pressing plate (or the optical cable tail fiber) of the longitudinal protection device is required to be disconnected;
rule 4: transformer protection device rules:
the connected network connection optical cable is disconnected when the transformer is protected and overhauled;
rule 5: one set of intelligent terminals eliminates the defect and the locking reclosing connection between the two sets of intelligent terminals is released;
description of the drawings: when the intelligent terminal is in a defect elimination state, due to the fact that a reclosing loop is locked, the reclosing function of a normally running line can be influenced.
The safety measure hard isolation rule is as follows: the hard isolation measures of the overhaul safety measure not covered by the SCD file are specifically as follows: a maintenance pressing plate, a tripping and closing pressing plate, a CT/PT terminal and the like.
Rule 1: the intelligent terminal tripping and closing hard pressing plate is protected or the intelligent terminal is overhauled and is switched off;
