Abstract
The invention discloses an improved 10kV high-voltage switch cabinet cable chamber misoperation-preventive locking method and belongs to high-voltage switch cabinet equipment. The improved 10kV high-voltage switch cabinet cable chamber misoperation-preventive locking method comprises the following steps: (1) arranging a high-voltage electric sensor at a high-voltage loop with an earthing knife-switch, additionally arranging an electric display device on a front cabinet door, connecting the high-voltage electric sensor with the electric display device, and enabling the earthing knife-switch to achieve an electric locking function with a cable chamber door directly; (2) arranging a reliable mechanical inter-locking device between the switch cabinet cable chamber door and an earthing switch, and achieving a mechanical locking function of an earthing knife and the cable chamber door; (3) fixing a rear door with loose leaves on one side and special bolts with lock hanging holes on bolt heads, instead of fixing bolts, on the other side. The defects that a misoperation-preventive locking system of a 10kV switch cabinet is imperfect, fed cables are still electrified after the switch is separated and great potential safety hazard can be caused are overcome, operators are prevented from entering a powered room by mistake, and the life security of the operators and the power generation equipment security are ensured.
Description
Technical field
The invention belongs to high-voltage switch gear cabinet equipment scope, the 10kV high-tension switch cabinet cable vault Interlocking Methods of particularly a kind of improvement.
Background technology
Ming Tombs, Beijing storage power plant 10kV station service electrical system is divided into three sections of single female power supplies, and be respectively 1G, 2G, 3G, 10kV switch cabinet system is air insulation metal armoured switchgear, within 1998 years, comes into operation.
The anti-error locking system imperfection of 10kV switch cubicle, because the 10kV system of Ming Tombs power plant is lower inlet wire, after switch separating brake, inlet wire cable is still charged, the forward and backward cabinet Men Junwu in the cable vault locking of switch cubicle, can open at any time, there is very large potential safety hazard, also not meet peace and arrange requirement.
Summary of the invention
The object of the invention is the 10kV high-tension switch cabinet cable vault Interlocking Methods proposing a kind of improvement, it is characterized in that, comprising:
1) arrange electrification in high voltage transducer in high tension loop place of disconnecting link with ground, front cabinet door installs charged display device additional, electrification in high voltage transducer is connected with charged display device; Make grounding switch directly and cable chamber door realize electric blocking function;
2) reliable mechanical interlocks is set between switch cubicle cable chamber door and earthed switch, is grounded cutter and cable chamber door mechanical latching function;
3) at the rear cabinet door that the half of bolt of half of loose-leaf is fixing, the set bolt of every block rear cabinet door is replaced by special bolts bolt head having lock-receiving aperture, and reaming is carried out to respective anchor site in rear door plate, during closing back door, reaming in rear door plate is enclosed within bolt head, this bolt head carries out padlock, only has and padlock releasing just can be opened back door;
4) therefore realize:
(1) only when cable vault is not charged, grounding switch just allows to be closed a floodgate;
(2) only when earthed switch is in "on" position, cable chamber door just allows to be opened;
(3) only when cable chamber door is closed, earthed switch just allows by separating brake.
The invention has the beneficial effects as follows the anti-error locking system imperfection overcoming 10kV switch cubicle, the forward and backward cabinet Men Junwu in the cable vault locking of switch cubicle, can open at any time, after switch separating brake, inlet wire cable is still charged, there is the defect of very large potential safety hazard, achieve (1) only when cable vault is not charged, grounding switch just allows to be closed a floodgate;
(2) only when earthed switch is in "on" position, cable chamber door just allows to be opened; (3) only when cable chamber door is closed, earthed switch just allows to be prevented between operations staff's mistakenly entering into charged by the function of separating brake, ensures life security and the generating equipment safety of operations staff.
Accompanying drawing explanation
Fig. 1 is electric blocking schematic diagram.
Fig. 2 is special bolts schematic diagram.
Fig. 3 is rear door of switch cabinet padlock schematic diagram.
Embodiment
The present invention proposes a kind of 10kV high-tension switch cabinet cable vault Interlocking Methods of improvement, is explained below in conjunction with accompanying drawing.This 10kV high-tension switch cabinet cable vault Interlocking Methods comprises:
1) in the electric blocking schematic diagram shown in Fig. 1, arrange electrification in high voltage transducer 2 in high tension loop place of disconnecting link with ground, front cabinet door installs additional charged display device 1, electrification in high voltage transducer 2 is connected with charged display device 1; Cable chamber door is installed latching electromagnet 3; Electrification in high voltage transducer 2 by electrification in high voltage whether signal transmission to charged display device 1, the charged situation of charged display device display high tension loop, output signal to latching electromagnet 3 simultaneously, when determining high-pressure side and being charged, latching electromagnet 3 closes cable chamber door, prevents between operations staff's mistakenly entering into charged.Therefore, grounding switch and cable chamber door is directly made to realize electric blocking function.
2) reliable mechanical interlocks is set between switch cubicle cable chamber door and earthed switch, is grounded cutter and cable chamber door mechanical latching function;
3) in the rear door of switch cabinet padlock schematic diagram shown in the special bolts schematic diagram shown in Fig. 2 and Fig. 3, at the rear cabinet door that the half of bolt of half of loose-leaf is fixing, the set bolt of every block rear cabinet door is replaced by special bolts bolt head having lock-receiving aperture, and reaming is carried out to respective anchor site in rear door plate, during closing back door, reaming in rear door plate is enclosed within bolt head, this bolt head carries out padlock (rear door of switch cabinet padlock schematic diagram as shown in Figure 3), only has and padlock releasing just can be opened back door.
4) therefore realize:
(1) only when cable vault is not charged, grounding switch just allows to be closed a floodgate;
(2) only when earthed switch is in "on" position, cable chamber door just allows to be opened;
(3) only when cable chamber door is closed, earthed switch just allows by separating brake.
Claims (1)
1. the 10kV high-tension switch cabinet cable vault Interlocking Methods improved, is characterized in that, comprising:
1) arrange electrification in high voltage transducer in high tension loop place of disconnecting link with ground, front cabinet door installs charged display device additional, electrification in high voltage transducer is connected with charged display device; Make grounding switch directly and cable chamber door realize electric blocking function;
2) reliable mechanical interlocks is set between switch cubicle cable chamber door and earthed switch, is grounded cutter and cable chamber door mechanical latching function;
3) at the rear cabinet door that the half of bolt of half of loose-leaf is fixing, the set bolt of every block rear cabinet door is replaced by special bolts bolt head having lock-receiving aperture, and reaming is carried out to respective anchor site in rear door plate, during closing back door, reaming in rear door plate is enclosed within bolt head, this bolt head carries out padlock, only has and padlock releasing just can be opened back door;
