Embodiment
For the purpose, technical scheme and advantage of the embodiment of the present invention are more clearly understood, below in conjunction with the accompanying drawings to this hair
Bright embodiment is described in further details.Here, the schematic description and description of the present invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
The art technology term being related in embodiments of the present invention is first briefly described below：
Equipotential live line work：Operating personnel makes the current potential of oneself body rise to charging member current potential by electrical connection, and
It is properly isolated from different potentials around, the operation directly carried out to live part.There are many defects on high voltage alive equipment, adopt
It is difficult processing with indirect operating method.The electrostatic field that operating personnel enters charging equipment directly operates, at this moment human body and electrical body
Potential difference is necessarily equal to zero, claims equipotential live line work.
In order to carry out bus isolating switch disconnecting lead operation in the case where ensureing security, the embodiment of the present invention is provided
A kind of method of bus isolating switch disconnecting lead.Fig. 1 is the method for median generatrix disconnecting switch disconnecting lead of the embodiment of the present invention
Flow chart, as shown in figure 1, this method can include：
S1, insulated platform is placed in below the bus for needing to carry out disconnecting switch disconnecting lead operation；
The job position that S2, operation insulated platform are risen to immediately below bus；
S3, the job position immediately below insulated platform Up Highway UHW, carry out equipotential disconnecting switch disconnecting lead operation.
Flow is it is known that in embodiments of the present invention as shown in Figure 1, and operator need not enter alternate carry out operation,
Bus isolating switch disconnecting lead operation can safely and effectively be implemented.
The method of bus isolating switch disconnecting lead in order to illustrate the embodiments of the present invention more clearly, is given below a tool
The implement scene of body is illustrated.Fig. 2 is the instantiation of the method for median generatrix disconnecting switch disconnecting lead of the embodiment of the present invention
Figure.As shown in Fig. 2 in this example, operating personnel need not enter alternate carry out operation, operating personnel stands in an insulated platform
On, rise to immediately below bus, disconnecting switch disconnecting lead is carried out to bus.Specifically, insulated platform is placed in by operating personnel
Need to carry out below the bus of disconnecting switch disconnecting lead operation, stand on insulated platform, then operate insulated platform to rise to mother
Job position immediately below line, this way it is not necessary to operating personnel, which enters the alternate position of bus, carries out equipotential, and bus just under
The operation of the equipotential disconnecting switch disconnecting leads of Fang Jinhang.In fig. 2, operating personnel to B phases bus carry out it is equipotential every
Leave shut-off and connect lead operation；Lead under disconnecting switch is shown in Fig. 2.Operating personnel can be operated exhausted by a control device
