Abstract
The utility model relates to an ultra-prevention protective low-voltage distribution cabinet. The distribution cabinet comprises a distribution cabinet body and panel components. The distribution cabinet is characterized in that the panel components are installed on a door of the distribution cabinet, an intelligent protector is arranged over the panel components, and breaker switches are arranged below the panel components; and that two emergency-stop buttons are arranged over the breaker switches, wherein one emergency-stop button is equipped with a flexible steel wire, and the other end of the flexible steel wire is connected with a forced-trip actuator. The distribution cabinet can carry out real-time detection and control protection on low-voltage power distribution lines and electrical equipment either before the power distribution lines and the electrical equipment are electrified or when the power distribution lines and the electrical equipment are electrified and operated, thereby carrying out advanced prevention and effective protection, and enabling power distribution equipment to run safely.
Description
Technical field:
The utility model relates to a kind of GGD type ultraprophylaxis protection low-voltage distribution cabinet; It is applicable to the running protection of electrical power trans mission/distribution system low-voltage complete switch equipment; To the leading prevention of low-voltage distributing line, power consumption equipment fault, simultaneously can energy-conserving and environment-protective, to guarantee the safe operation of outdoor electricity distribution equipment.
Background technology:
At present; Through relaying protection or killer switch sectionalised protection etc., these protections all are protections that distribution line or the power consumption equipment accident after low-voltage complete switch equipment puts into operation sent sound and light alarm or tripping operation realization when taking place to known electrical power trans mission/distribution system low-voltage complete switch equipment in the back of putting into operation.Yet; For some reason sometimes electric fault but just oneself closes behind the main switch existence of failover when equipment puts into operation through existing before equipment puts into operation; If the splendid meeting of killer switch protective value this moment moment disjunction; Though circuit or power consumption equipment are protected, just realized, do not accomplish to prevent trouble before it happens this moment.If but this moment, the killer switch protective value was good enough then can cause and prolong or tripping, caused damage even loss of life or personal injury for distribution line or power consumption equipment.
Summary of the invention:
The purpose of the utility model will provide a kind of ultraprophylaxis protection low-voltage distribution cabinet exactly, and it can overcome existing equipment and exist
Above problem.
The purpose of the utility model is to realize like this; Ultraprophylaxis protection low-voltage distribution cabinet comprises power distribution cabinet cabinet, panel component, and it is characterized in that: panel component is installed on the power distribution cabinet cabinet body door; The top of panel component is provided with intellective protector, and its below is provided with killer switch; Described killer switch is provided with two scram buttons, and one of them scram button is provided with stone dead wire, and the other end of described stone dead wire connects with forcing the dropout actuator.
The utility model provides a kind of and can before distribution line and power consumption equipment are switched on operation, not protect with operating real-time detection of energising and control.It can guarantee low-voltage distributing line and power consumption equipment before energising operation not with the operating leading prevention of energising with effectively protect, make the controller switching equipment safe operation.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model killer switch structural representation.
1. power distribution cabinet cabinet, 2. intellective protector, 3. panel component, 4. killer switch is 5. forced dropout actuator, 6. stone dead wire, 7. scram button.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further;
Ultraprophylaxis protection low-voltage distribution cabinet comprises power distribution cabinet cabinet 1, panel component 3, it is characterized in that: panel component 3 is installed on 1 of the power distribution cabinet cabinet, and the top of panel component 3 is provided with intellective protector 2, and its below is provided with killer switch 4; Described killer switch 4 is provided with two scram buttons 7, and one of them scram button 7 is provided with stone dead wire, and the other end of described stone dead wire 6 connects with forcing the dropout actuator.
During practical implementation; In Fig. 1; This device is with the electric current in the distribution line. and voltage parameter, insulation resistance parameter, humiture parameter, each parameter of respectively confirming switching value calculate respectively; Result of calculation is sent into protection and is started storage, and the data of storing are carried out logic discrimination and corresponding output more one by one.
1. before the operation:
1.1 then export the permission operating instruction when result satisfies service conditions when differentiating, promptly the controller switching equipment main switch allows to close a floodgate;
Though 1.2 have fault in the circuit but fault parameter does not reach as yet and forbids moving threshold values, export the acousto-optic pre-alarm this moment, allow operating instruction, promptly the controller switching equipment main switch can close a floodgate;
1.3 it is differentiated the result and then exports sound and light alarm this moment for can not satisfy service conditions the time, forbids operating instruction when there being fault in the circuit, i.e. controller switching equipment main switch No switching on;
1.4 when this device run duration of not switching on, the backplate opened on the ventilation hole is in closed condition.
2. in service:
2.1 then export when satisfying service conditions and allow operating instruction controller switching equipment main switch maintenance "on" position when differentiating the result;
Though 2.2 have fault in the circuit but fault parameter does not reach threshold values out of service as yet, export the acousto-optic pre-alarm this moment, keep allowing operating instruction, the controller switching equipment main switch keeps "on" position;
2.3 then export trip command jumping controller switching equipment main switch when the result continues service conditions for not satisfying when differentiating;
2.4 then export trip command jumping controller switching equipment main switch when differentiating when the result continues service conditions for not satisfying, if the trip gear of circuit breaker main switch is out of control, then wink speed output is forced to thread off and is instructed, and forces disjunction.
In Fig. 2; After ultraprophylaxis intellective protector (2) powers on; Ultraprophylaxis intellective protector (2) promptly begins data acquisition; With the electric current in the distribution line. voltage parameter, insulation resistance parameter, humiture parameter, respectively confirm parameter sample collection such as switching value; And the various parameters of sample collection are sent into transformation calculations module classify conversion and calculating in the lump, its result sends into the logic discrimination module and compares calculating with the parameter that presets, and will compare result calculated again and send into protection and start the result that module classification calculates protection output; Again with its object command export respectively send into allow operation, forbid moving, driving output control module that tripping operation, sound and light alarm, pressure are threaded off and formed, finally realize protection control.
In Fig. 2, panel component (3) is installed on power distribution cabinet cabinet (1) door, in order to indicate or manually to control killer switch (4).
In Fig. 3, when receiving pressure that the ultraprophylaxis intellective protector sends when threading off instruction, force dropout actuator (5) move immediately, through being connected of stone dead wire (6) and scram button (7), make killer switch (4) disjunction by force, realize reliable disjunction protection.
