Description
Technical field
The utility model relates to high-tension switch cabinet technology used in electric power system, especially relates to a kind of high-tension switch cabinet that is provided with arc protection structure.
Background technology
High-tension switch cabinet is transmission facility conventional in electrical power transmission system, mainly formed by electrical equipment zero devices such as on-load switch, fuse and motor-operating mechanisms, described motor-operating mechanism switches on and off for operational load switch, utilizes described motor-operating mechanism people just can in the Control Room of high-tension switch cabinet, carry out remote operation to high-tension switch cabinet.The problem existing is: high-tension switch cabinet only relies on fuse to carry out error protection to the transmission line circuit of high-tension switch cabinet conventionally, and when transmission line circuit breaks down while causing electric current excessive, the fuse on transmission line circuit can blow, thereby transmission line circuit is realized to protection.But because cable joint is aging, dirt, a variety of causes such as make moist, can cause cable joint generation electric discharge phenomena, thereby produce arclight.Electric discharge for a long time, arc burning, can cause cable joint to burn out, and high-tension switch cabinet explosive incident even occurs, and brought life danger, economy and emotional distress to enterprise, society and the people.Therefore entirety sees that the defencive function of high-tension switch cabinet is on the low side, has reduced safety in utilization and the reliability of high-tension switch cabinet.
Summary of the invention
Main goal of the invention of the present utility model be to provide a kind of can be to high-tension switch cabinet realize the high-tension switch cabinet arc protection structure of arc protection into and out of line loop.
The utility model technical scheme used is: a kind of high-tension switch cabinet arc protection structure, comprises arc photosensor, arc light controller; A described arc photosensor is set near the cable joint of the each on-load switch on inlet wire and the transmission line circuit of high-tension switch cabinet, arc light controller is provided with the switching circuit by arc photosensor control, the start button parallel connection of the operating electrical machines on the respective electrical pneumatic operating mechanism on the switch of described switching circuit and the inlet wire of high-tension switch cabinet or transmission line circuit.
The utility model, near the cable joint of the each on-load switch on inlet wire and transmission line circuit in high-tension switch cabinet, all establish an arc photosensor, an arc light controller of each arc photosensor configuration, in the time that the cable joint of on-load switch produces arc light, arc photosensor can capture arc light, thereby the power supply of making operation motor, operating electrical machines is switched on and is started motor-operating mechanism disconnection on-load switch, thereby high-tension switch cabinet is shielded, can prevent that electric discharge from appearring in high-tension switch cabinet, arc burning catches fire and explosion accident, thereby improve safety in utilization and the reliability of high-tension switch cabinet.
As preferably, the utility model also comprises the accident indicator being located on monitoring high-voltage switch screen, the switching circuit electrical connection on described accident indicator and arc light controller.This preferred version, when the cable joint of an on-load switch occurs arc light and causes while opening circuit, corresponding accident indicator is started working, and indicating to people is that arc fault appears in that on-load switch, is convenient to people high-tension switch cabinet is carried out to repair and maintenance.
As preferably, described accident indicator or be photoflash lamp alarm, or be voice guard, or be audible-visual annunciator.
As preferably, described arc light controller is located in the Control Room of high-tension switch cabinet.This preferred version, arc light controller, by the storage battery power supply in the Control Room of high-tension switch cabinet, can ensure still can normally work in the time of power circuit power-off, improves the protective effect to high-tension switch cabinet.
In sum, the beneficial effect that the utility model brings is: can realize arc protection to high-tension switch cabinet, improve safety in utilization and the reliability of high-tension switch cabinet.
Brief description of the drawings
Fig. 1 is a kind of electrical block diagram of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the utility model comprises arc photosensor 1, arc light controller 2; A described arc photosensor 1 is set near the cable joint of the each on-load switch on inlet wire and the transmission line circuit of high-tension switch cabinet, arc light controller 2 is provided with the switching circuit of being controlled by arc photosensor 1, and the button 4(of the operating electrical machines 3 on the respective electrical pneumatic operating mechanism on the switch 2.1 of described switching circuit and inlet wire or the transmission line circuit of high-tension switch cabinet is arranged on the monitor screen of Control Room of high-tension switch cabinet) parallel connection.As preferably, described arc light controller 2 is located in the Control Room of high-tension switch cabinet, it is an open type direct current relay, powered by the storage battery 6 being located in the Control Room of high-tension switch cabinet, the contact of this direct current relay forms the switch 2.1 of switching circuit, described arc photosensor 1 is connected on the wire loop of this direct current relay, in the time there is not arc light in high-tension switch cabinet, arc photosensor 1 is in high value state, wire loop is equivalent to off-position, the contact of this direct current relay is in off-state, in the time there is arc light in the cable joint of the on-load switch in high-tension switch cabinet, after corresponding arc photosensor 1 receives arc optical signal, resistance reduces, the wire loop energising of corresponding direct current relay, the closing of contact of this direct current relay, thereby connect the power supply of the operating electrical machines 3 of corresponding motor-operating mechanism, operating electrical machines 3 starts breaks corresponding on-load switch, thereby high-tension switch cabinet is shielded.For the ease of checking, the generation part of analysis of failure, the utility model is also provided with the accident indicator 5 being located on monitoring high-voltage switch screen, switching circuit electrical connection on described accident indicator 5 and arc light controller 2, wherein said accident indicator 5 or be photoflash lamp alarm, or be voice guard, or be audible-visual annunciator, the present embodiment is preferably audible-visual annunciator, described accident indicator 5 one end are connected with the positive pole of storage battery 6, the other end is connected with one end that corresponding arc photosensor 1 is connected with the coil of arc light controller 2, thereby realize the switching circuit electrical connection on accident indicator 5 and arc light controller 2, when after arc photosensor 1 receives arc optical signal, resistance reduces, accident indicator 5 is switched on and is sent sound and light alarm signal.
The specific embodiment of the above is only preferably execution mode of the utility model, not limits concrete practical range of the present utility model with this.The equivalence variation that all shapes according to the utility model, structure are done ought to all be included in protection range of the present utility model.
