Description
Technical field
The invention discloses one to be able to ensure that when operator carry out local operation to grid circuit breaker and on-load switch
The switch local operation safety device of personal safety, relates to the generating of power system, transmission of electricity, distribution, electricity consumption and automatization thereof
Technical field.
Background technology
Along with the new forms of energy such as photovoltaic, wind-force, energy storage, electric automobile and the extensive access of application apparatus thereof, intelligentized
The development of power distribution network, micro-capacitance sensor and Demand-side will become the Main way of traditional mode power network development, intelligentized power distribution network,
Micro-capacitance sensor, Demand-side have become current and whole world electrical network in the future emphasis investment and developing direction.
2kv 66kv chopper or on-load switch (hereinafter referred to as: switch or switch cubicle), be as intelligentized distribution
Net, micro-capacitance sensor, the key equipment of Demand-side.At present, this kind of switch, when carrying out local operation, is all straight with hands by operator
It is connected on switch cubicle and operates, it is achieved the on/off switch of switch controls, as long as it is characterized in that when operator are by the control of switch
Mode is set to control mode (operation on the spot/distant place button or handle) on the spot, and operator directly press the conjunction of switch cubicle with hands
When dividing the button of button, operating handle, protection control device, switch action at once and realize on/off switch operation, this moment switch and people
The distance of body is exactly the length of staff.
Switch is in on/off switch course of action, especially in the case of charged, during situation flashing occur, even exploding
Having generation, current power distribution network is in order to improve power supply reliability, and the circuit of many ring network power supplies, all using does not has a power failure turns supplier of electricity
Formula, the switch that most both sides of all being closed at the scene by operator are the most charged, carry out the grid-connected electrically operated of cyclization point, this
Generic operation occurs the probability of these dangerous phenomenons to be substantially increased, and this dangerous situation once occurs, with regard to entail dangers to operator
Life security.
At present, when common demands switch now operates in the world, operator are required to put on preventing arc (arclight) clothes
Dress just can carry out local operation, for the switch cubicle that some operation times are long, then takes only to carry out not charged on/off switch behaviour
Make.These measures, can only slow down danger, it is impossible to eliminate and stop the threat to operator's life security, this not only lowers
The power supply reliability index of power distribution network, also brings hidden danger to power grid security, stable, economic operation.
Patent of the present invention discloses a kind of switch local operation safety device, and this device uses embedded SoC software and hardware
Technology and protecting electrical power system, monitor, control technology, by real-time data acquisition, calculate, process and status monitoring, human body
Induction monitoring, the method for action delay, it is ensured that operator are when carrying out switching on/off switch operation on the spot, it is to avoid switch occurs arc
Light, explosion hazard are to the life security of operator, it is achieved the on/off switch hot line job on the spot of switch safety.
This safety device is so that the switch of various 2KV to 66KV avoids due to Switch main body or operation of power networks work
Condition occurs arc light or blast to jeopardize the life security of operator when causing switching on/off switch operation on the spot, and this is to improving power supply
Security reliability, the operation to electricity net safety stable economy has the most great meaning.
Summary of the invention
Switch local operation safety device is controlled by PT, CT input, on off state input, human body sensing probe, on/off switch
Output, CPU, display and guidance panel, communication interface composition (see figure 1).
The CT electric current input of device includes that Ia, Ib, Ic, In, the input of PT voltage include bus VBa, VBb, VBc, VBn, and
Optional circuit VLa, VLb, VLc, the voltage input of VLn circuit can use the input side of capacitor voltage sensor construction
Formula；State input accesses the auxiliary contact position of switch and closes the criterion of point state as switch, isolation switch, grounding switch, little
Report to the police in truck position, gas low pressure, human body sensing probe signal inputs as status condition；On/off switch controls output and accesses switch
Secondary circuit realizes the conjunction sub-control system of switch；Guidance panel includes LCD touch screen, on/off switch button, performs cancel button.
Safety device realizes operator's security protection when local operation switchs to personnel by following functions:
1 Real-time Collection calculate switch operational factor and state, and with set parameter and model comparision, if allow on the spot
Manual closing operation or point
In the regulation parameter of lock, model domain, switch can carry out the artificial operation of on/off switch on the spot, and otherwise, operator no matter
Carry out closing a floodgate or sub-switching operation, its output control loop miss operation, and provide alarm；
2 detection judge operator whether in the deathtrap of switch motion, if setting region in sense that human body is believed
Number, device will refusal
Send on/off switch control command, forbid switching on/off switch, and provide alarm；
3 press combined floodgate or opening button after, this device can automatically by presetting time delay a period of time, then by control loop
Output divide-shut brake control
Signal processed, to the divide-shut brake loop of switch, can set this period of time delay (such as 10 seconds, 20 seconds etc.) as required, and it is made
With being to allow operator have time enough leave the enough distances of Switch main body and enter the region of a safety, even if switching
Strength electric arc is occurred even to explode during action, the most not entail dangers to personal safety；One is had time delay to fall to count on a display panel
Time window, allowing the operator to be clearly seen switch will time of action；Before countdown is zero, operator can be with
Time press cancellation button, remove controls operation execution.
This device is typically mounted on the door-plate in switch cubicle front, can realize data with miscellaneous equipment and system communication
Exchange, interoperability function；This device can also be with other such as protective relaying device, switch manipulation instrument, intelligent end device
Combine together, it is achieved one comprise safety operation on the spot, protect, measure, control, the switch intelligent terminal of communicating integral.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of switch local operation safety device；
1. display operating panel can show various figure and data, but after operator press combined floodgate or separating brake button, i.e.
Carving and eject time delay countdown window, the movement time of suggestion device on/off switch outlet, if device monitoring is the most artificial to not meeting
The parameter of operation and pattern, provide alarm.
2., when human body sensing probe detection is to human body, closed bite separating brake is exported by device, the installation site of probe and detection
Scope determines according to field condition, and primary condition is when switch occurs arc light or explosion time switch to have enough distances to keep away with human body
Exempt to injure life safety.
