Abstract

The utility model relates to novel indoor metal armored withdrawable switching equipment mainly comprising a cabinet body and a withdrawable handcart, wherein the cabinet body is in an assembly type structure; main electrical components of the switching equipment are all provided with separate compartments respectively, such as a circuit breaker chamber, a busbar chamber, a cable chamber and an instrument chamber; the cable chamber is positioned at the lower part of the cabinet body and internally provided with a cabinet-held cable, a ground switch, a current transformer and a condensation device; the busbar chamber is positioned at the upper-rear part of the cabinet body and internally provided with a main busbar and branch busbars; the instrument chamber is positioned at the front-upper part of the cabinet body; the circuit breaker chamber is positioned at the front-middle part of the cabinet body; the current transformer is hoisted in the cable chamber positioned at a lower baffle plate of the busbar chamber; and the ground switch is installed on a baffle plate positioned at the middle part of the cable chamber. The utility model has the advantages that the current transformer is hoisted downwards, thereby enlarging the effective utilization space of the cable; the ground switch is installed in the cable chamber and on the middle baffle plate, thereby improving the synchronization and the closing speed of the ground switch; and a whole rear door is changed into an upper door and a lower door so that the doors can be opened and closed more flexibly.

Description

Novel indoor metal armoring draw out switchgear
[technical field] the utility model relates to high-voltage appliance switch equipment, promptly a kind of novel indoor metal armoring draw out switchgear.
[background technology] indoor metal armoring draw out switchgear is 3.6~12kV three-phase alternating current the complete sets of equipment, is mainly used in to accept and the distribution electric energy, and circuit is carried out control, protection and monitoring.Cabinet is mainly assembled with securing member by Digit Control Machine Tool processing (promptly cut, dash, roll over) back by import aluminizing zinc steel plate.On the cabinet top board pressure relief device is arranged, the cabinet door has the louvre that satisfies degree of protection, whole metal armoring draw out switchgear mainly contains control room, breaker chamber, bus-bar room and cable vault, the middle circuit breaker cart is housed in the breaker chamber, can extract out, be convenient to on-the-spot installation, debugging and maintenance, identical circuit breaker cart can exchange, main bus bar and branch bus are housed in the bus-bar room, and main bus bar is fixed by branch bus and bus casing and fixed contact box.Main bus bar and branch bus are with phase-splitting look thermoplastic tube thermoplastic in addition, current transformer is housed in the cable vault, and current transformer is contained in the upper back, cable vault, earthed switch is contained in the rear lower of cable vault, carry out locking by mechanical interlocking and circuit breaker, realize " five is anti-" function, condensation device pack into bottom, cable vault or side, connect the condensation device by sensing function and make its work, on the door electrification display is housed before and after the cable vault simultaneously.Because above-mentioned many functions and advantage, having obtained the user approves widely, but in use also find some shortcomings and disadvantage: 1, in the cable vault, current transformer is installed in the upper back of cable vault, earthed switch is contained in the rear lower of cable vault, and inconvenient site operation personnel install, debug and maintenance.2, the back door is a monoblock, and the switch door is relatively required great effort, and is dumb, and " five is anti-" function is poor.
[summary of the invention] is in order to overcome in the present indoor metal armoring draw out switchgear, the space is narrow and small in the cable vault, maintenance is inconvenient, the inflexible shortcoming of back door switch the utility model proposes the new design of the novel indoor metal armoring draw out switchgear that a kind of internal structure adjusts to some extent.
This novel indoor metal armoring draw out switchgear, mainly form by the two large divisions, it is cabinet and can extract handcart out, handcart is divided into middle circuit breaker cart or other function handcart, and cabinet is processed through Digit Control Machine Tool with import aluminizing zinc steel plate, and adopt multiple flanging technology, make whole cabinet not only have the precision height, very strong anticorrosive and non-oxidizability, mechanical strength height, good looking appearance, cabinet adopts modular construction, forms with staking nut and high-intensity Bolt Connection, and the main electric elements of switchgear all have its independently compartment, that is: breaker chamber, bus-bar room, cable vault, control room; Degree of protection all reaches IP2X between each compartment, and the cable vault is in the cabinet bottom, indoor being equipped with into cabinet cable, earthed switch, current transformer and condensation device, and the rear portion is a bus-bar room on the cabinet, indoor main bus bar and the branch bar of being equipped with; Front upper part is the control room, and various instrument and meters are housed; Front middle part is a breaker chamber, it is characterized in that, current transformer is lifted in the cable vault of bus-bar room lower clapboard, and earthed switch is installed on the dividing plate at middle part, cable vault.
The back door of cabinet is divided into upper and lower two parts, and is corresponding with bus-bar room and cable vault respectively.
Cabinet is regular cuboid, and promptly four faces in front, rear, left and right are contour.
The utility model has the advantages that: 1, current transformer changed down lifting by installing originally backwards, made it increase cable and effectively utilized the space, saved copper bar, was convenient to on-the-spot installation, debugging, safeguarded and maintenance.2, earthed switch is retrofitted on the median septum by installing behind the original cabinet in the cable vault, makes the more close operating point of earthed switch like this, and is laborsaving, improved the synchronism of earthed switch and closed sum velocity, also reserved more installation, maintenance, space for maintenance to the user.3, the back door changes two doors up and down into by a whole door, and upper and lower two one side fix with hinge, makes that the switch of door is more flexible, between simultaneously upper and lower door and the earthed switch operating mechanism locking is arranged, and satisfies product five and prevents functions.4, increase the charged and earthed switch blocking function of feeder line, can prevent splice grafting ground, the charged pass of ring network power supply switch.
[description of drawings] Fig. 1 is the utility model front view
Fig. 2 is the left view after the utility model unloads the cabinet side plate
Fig. 3 is the utility model rearview (having the part to cut looks)
Among the figure: 1, cable vault, 2, earthed switch, 3, earthed switch auxiliary contact box, 4, the earthed switch operating mechanism, 5, the circuit breaker cart chamber, 6, control room, 7, bus-bar room, 8, bus, 9, current transformer, 10, Xiamen, back, 11, the back door blocking mechanism, 12, the back to the doorstep, 13, median septum.
[embodiment] is described in detail as follows embodiment of the present utility model below in conjunction with accompanying drawing:
