Abstract
A separate type secure low voltage capacitance compensation device comprises a cabinet body divided into five functional chambers, namely a busbar chamber, a capacitor chamber, a switch chamber, an instrument chamber and a control cable channel, wherein capacitors are mounted in the capacitor chamber; main busbars are mounted in the busbar chamber; secondary electrical apparatus elements are mounted in the instrument chamber; control wires of a distribution automatic control system are arranged in the control cable channel; a main switch, a fuse, a contactor and a thermorelay are mounted in the switch chamber; all the elements in each functional chambers are connected into a main electrical loop through bus bars or cables; and an operating handle is connected with the main switch. The functional chambers are well isolated from each other, so that the influence of element failures is limited within the respective chamber; and the main switch adopts an out-cabinet operation mode, so that the cabinet door can not be opened only when the power is off, so as to better ensure the safety of operating staff.
Description
Technical field
The utility model relates to a kind of electrical control gear, particularly the low-voltage capacitance compensating device.
Background technology
Existing low-voltage capacitance compensating equipment does not generally carry out the built-in function unit separation, though or separation arranged, and not exclusively.Capacitor in the compensation equipment often causes leakage because of sole mass and mains by harmonics factor, contactor also has the arcing phenomenon after inefficacy, because of device interior is not reliably separated, possibility is because of other element of damage of individual elements, even ignition capacitance compensation equipment.In addition, electrified body is not taked safeguard procedures in the existing capacitance compensation equipment, also operating personnel is caused potential safety hazard.
The utility model content
The utility model aims to provide a kind of cellular-type safety-type low-voltage capacitance compensating cabinet, can be because of other element of damage of individual elements, and safe, easy to operate.
Technical solutions of the utility model are: a kind of cellular-type safety-type low-voltage capacitance compensating device, comprise cabinet, be divided into bus-bar room in the cabinet, the electric capacity chamber, the switch gear room, the control room, five functional compartments of control cable passage, capacitor is installed in the electric capacity chamber, main busbar is installed in bus-bar room, the secondary electric elements are installed in the control room, the control line of power distribution automation control system is arranged in the control cable passage, main switch, fuse, contactor, thermal relay is installed in the switch gear room, element in each functional compartments connects into main electric loop by bus row or cable, and operating grip links to each other with main switch.
Described fuse, contactor, thermal relay are installed on the detail assembly panel.
The modularization installing hole is arranged on the described detail assembly panel.
The fuse dividing plate is installed between the described fuse.
Carried out good isolation between the functional compartments of the present utility model, in the interval, main switch adopted the outer mode of operation of cabinet, just can open the cabinet door after the outage, has guaranteed operating personnel's safety preferably under the element fault coverage was limited in.Control elements such as fuse, contactor, thermal relay adopt facade to install, and easy-maintaining directly perceived adopts the transparent insulation bent plate to separate between the fused mass of fuse, touch the short circuit phenomenon that terminals cause in the time of can effectively avoiding changing fuse because of carelessness.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model control element facade is arranged schematic diagram.
Among the figure: 1-cabinet, 2-capacitor chamber, 3-capacitor, 4-bus-bar room, 5-master's busbar, 6-control cable passage, the 7-control room, 8-main switch, 9-operating grip, 10-branch row, 11-switch gear room, the 12-fuse, 13-contactor, 14-thermal relay, 15-fuse dividing plate, 16-detail assembly panel.
Specific embodiments
As shown in Figure 1, the utility model cabinet 1 adopts the assembled structure of C section bar combination, can carry out installed part easily and arrange, realizes multiple electric scheme.The 2mm steel plate will be divided into five functions at interval in the cabinet: capacitor chamber 2, bus-bar room 4, control cable passage 6, control room 7, switch gear room 11.Main element is a capacitor 3 in the capacitor chamber 2, be mainly main busbar 5 in the bus-bar room 4, control cable passage 6 is as the control line passage of power distribution automation control system, the secondary electric component can be installed by control room 7, be elements such as main switch 8, fuse 12, contactor 13, thermal relay 14, branch row 10 in the switch gear room 11, cable passes the element between the cable-through hole linkage function chamber of dividing plate.Because functional compartments has been carried out effective separation, its influence was indoor under being limited in when the element in a certain functional compartments broke down, reduced fault incidence, guaranteed that the easy fault element of sending out such as capacitor 3, contactor 13 produces serious consequence at the Shi Buhui that breaks down.
Operating grip 9 links to each other with main switch 8, in cabinet 1 outside main switch 8 is carried out the branch closing operation, after having only the outage of main switch 8 separating brakes, just can open the cabinet door, can guarantee in the switch gear room 11 this moment not charged, guarantee that the operation maintenance personnel to the security incident of the time can not getting an electric shock of element maintenance in the cabinet, have improved fail safe.
As shown in Figure 2, control elements such as fuse 12, contactor 13, thermal relay 14 are installed on the mounting panel 16 with modularization hole, can realize different elements combination layout easily, have improved the standardization level of making.Cut off with fuse dividing plate 15 between the fuse 12, touch terminals in the time of can effectively avoiding changing fuse because of carelessness and cause short circuit to take place.Control element is installed for facade on mounting panel 16, does not have between the element and blocks, and operating state comes into plain view, and is convenient to maintenance test.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
