Specific embodiment
Understand in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, with reference to the accompanying drawing to this hair
Bright embodiment is described in further details.Here, the illustrative embodiments of the present invention and their descriptions are 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 that directly live part is carried out.There are many defects on high voltage alive equipment, adopts
It is difficult to handle 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 guaranteeing safety, 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 of embodiment of the present invention disconnecting switch disconnecting lead
Flow chart, as shown in Figure 1, this method may include：
S1, insulated platform is placed in below the bus for needing to carry out disconnecting switch disconnecting lead operation；
S2, operation insulated platform rise to the job position immediately below bus；
S3, the job position immediately below insulated platform Up Highway UHW carry out equipotential disconnecting switch disconnecting lead operation.
It is known that in embodiments of the present invention, operator does not need to enter alternate carry out operation process as shown in Figure 1,
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 specific example of the method for median generatrix of embodiment of the present invention disconnecting switch disconnecting lead
Figure.As shown in Fig. 2, in this example, operating personnel does not need to enter alternate carry out operation, and operating personnel stands in an insulated platform
On, it rises to immediately below bus, disconnecting switch disconnecting lead is carried out to bus.Specifically, insulated platform is placed in by operating personnel
It below the bus for needing to carry out disconnecting switch disconnecting lead operation, stands on insulated platform, then operates insulated platform and 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 lead of Fang Jinhang.In Fig. 2, operating personnel to B phase bus carry out it is equipotential every
It leaves shutdown and connects lead operation；Lead under disconnecting switch is shown in Fig. 2.Operating personnel can be operated exhausted by a control device
Edge platform rises to the job position immediately below bus.The control device of insulated platform is not shown in Fig. 2, which can be set to
On insulated platform, or other positions can also be set to, such as insulated platform can be controlled by way of remote control.Utilize the control
Device processed can make insulated platform lifting or shift position.
When it is implemented, operation insulated platform rises to the job position immediately below bus, including：Keep insulated platform and side
The safe distance of phase, may further ensure that safety in this way.In Fig. 2, operating personnel to B phase bus carry out it is equipotential every
It leaves shutdown and connects lead operation, keep the safe distance of insulated platform and A phase bus and C phase bus.

Job position, including：Insulated platform is operated, until two gag lever posts erect on insulated platform are aligned with bus；Wherein, this two
Plane where root gag lever post passes through the central point of insulated platform.In fig. 2 it is shown that the position of two gag lever posts, this two
Gag lever post is located at the edge of insulated platform, and certainly in other embodiments, this two gag lever posts can also be located at insulated platform
Upper other positions, such as have a certain distance with the edge of insulated platform, this is not limited by the present invention, and relevant change case is equal
Protection scope of the present invention should be fallen into.Plane where two gag lever posts passes through the central point of insulated platform, it is ensured that insulation
Platform is in operating personnel in the position range of safety immediately below bus.
In operation process, threat of the operating personnel by adjacent phase bus energized conductor, operating personnel stretches once neglecting to have
The movement such as hand, human body is just difficult to ensure enough alternate safe distances with adjacent phase bus energized conductor, therefore, in order to further
Guarantee operation safety, the insulated guardrail of limitation personnel activity can be installed on insulated platform, to guarantee operating personnel in safety
Operation in range.Equipotential disconnecting switch disconnecting lead operation is then carried out, may include：The insulated guardrail on insulated platform
It limits in range, carries out equipotential disconnecting switch disconnecting lead operation.Human body is in equipotential, ground of the human body to ground at this time
