Description
Technical field
The present invention relates to power switchgear technical fields, and in particular to a kind of coupling type cable chamber door and earthing switch join
Lock control method.
Background technique
High-tension switch gear refers to voltage rating 1kV or more, is mainly used for cut-offfing and closing the electric appliance of galvanic circle, is
The components such as its corresponding control of high-voltage switch gear, measurement, protection, regulating device and auxiliary, shell and support and its it is electrical and
The general name of mechanical connection composition, is to turn on and disconnects the important control equipment of circuit, excision and isolated fault.
There are two types of earthing switches: inspection earthing switch and high speed grounding switch.High speed grounding switch is that have centainly to close
A kind of earthing switch of specific use of short circuit current ability.After line-to-ground fault is removed, supplied by adjacent working line
The secondary arc current of electric forming faulty line, is closed using high speed grounding switch, can eliminate secondary arc current, then quick-speed turning on-off ground connection is opened
It closes, it is ensured that route automatic reclosing can succeed.Inspection earthing switchgear distribution only plays disconnected beside the disconnecting switch of breaker two sides
The effect of two sides ground connection when road device overhauls；And high speed grounding switch configuration leans on route one in the outlet disconnecting switch of transmission line circuit
Side, its effect are as follows: the capacitance current and electromagnetic induction generation inductance electricity that folding parallel aerial route is generated due to electrostatic induction
Stream；When there is creepage phenomenon or interior of shell arcing in interior of shell insulator, high speed grounding switch by major loop rapid grounding,
Fault current is cut off using breaker.
Since the voltage of high-tension switch gear is high, for the personal safety for ensureing operation and maintenance personnel, prevent operator from missing
Enter and charge compartment, high-tension switch gear need to install safe and reliable interlock, meet " five is anti-" locking and require.Wherein under cabinet body
Interlock requirement between door and earthing switch is specific as follows: when high-tension switch gear is run, earthing switch is in gate-dividing state, band
The cabinet body Xiamen of electric compartment forbids opening, to ensure operational safety.It, must after switch has a power failure when needing to overhaul equipment
Earthing switch in cabinet must be made to be in "on" position, i.e. interior of the cabinet safety ground, cabinet body Xiamen could open.This set is wanted
It asks primarily to prevent the maloperation to high voltage isolator, prevents personnel's electrification from entering cable vault and overhaul and safeguard,
The generation for preventing peril.In addition, when catastrophic failure occurs for equipment, and in the case that earthing switch can not close a floodgate, Ying You
Emergency release mode can quickly open cabinet body Xiamen.Structure is complicated for the mechanical interlocks of current cable vault's cabinet door, passes
Dynamic process is cumbersome, and mechanism is easy to appear clamping stagnation or necrosis, the defect at service life bottom.
Summary of the invention
To be solved by this invention is that structure is complicated for the mechanical interlocks of current cable vault's cabinet door, and transmission process is numerous
Trivial, the technical issues of mechanism is easy to appear clamping stagnation or necrosis, service life bottom, is, and it is an object of the present invention to provide a kind of coupling type cable chamber door
