Embodiment
The present invention is special in being pressed into the cover switch cubicle in the regional development below the high height above sea level 4000m.Design by the armouring metal enclosed switchgear among the GB3906-91.
Be pressed into the cover switch cubicle in a kind of, by fixing cabinet 1 with can extract the parts two large divisions out and forms, the shell of cabinet and the dividing plate of each functional unit all adopt Bolt Connection.The switch board housing degree of protection is IP4X, and the degree of protection when the breaker chamber door is opened is IP2X.Switch cubicle can be mounted to dual cabinet and arrange, and promptly is mounted to back-to-back or face-to-face double arrangement.
The shell of switch cubicle and dividing plate are by covering aluminium zinc steel plate through the CNC machine tooling; And take multiple flanging technology; Make whole cabinet not only have the precision height; Very strong anticorrosive and antioxidation, and owing to adopt multiple flanging technology to make cabinet lighter than other same category of device cabinet overall weight, mechanical strength is high.Cabinet adopts modular construction, forms with staking nut and high-intensity Bolt Connection, makes the processing cycle short like this, and component universality is strong, and floor space is few, is convenient to tissue production.Switch cubicle is separated into cable vault 2, bus-bar room 3, relay control room 8, handcart chamber 9, the equal independent grounding of each compartment shell.The door of switch cubicle adopts workmanship of spraying plastics, makes its surperficial shock resistance, and is corrosion-resistant, guaranteed the attractive in appearance of profile.
The handcart skeleton adopts steel plate after the CNC machine tooling, to rivet and forms.Handcart and cabinet insulation coordination, mechanical interlocking, safe and reliable flexible.Handcart has isolated location, test position and service position in cabinet, each position is equipped with positioner, and is reliable to guarantee interlocking, must operate by interlocking anti-misoperation program.When handcart is removed cabinet when needs,, just can conveniently extract out, carry out various inspections, maintenance with a special transfer vehicle.
Main electric component in the switch cubicle all has its independently compartment, that is: cable vault 2, bus-bar room 3, relay control room 8, handcart chamber 9.Each compartment degree of protection all reaches IP2X; Except that the control room, other three compartments all have pressure release passage respectively.
(1) rear wall of cable vault 2 can be installed current transformer, voltage transformer, and earthed switch also can be installed lightning arrester in the cable vault.After handcart and horizontal baffle are removed; The workmen just can get into switch cubicle from the front cable is installed, and in the cable vault, is provided with specific cable bonding conductor, can and connect 1-6 root list stamen cable; Simultaneously also prepare the Demountable metallic shrouding, to guarantee the convenience of site operation in its underpart.
(2) bus of bus-bar room 3 causes another switch cubicle from a switch cubicle, fixes through branch bar and fixed contact box.Main bus bar and interbus are the fillet copper bar of square-section, need use two rectangular bus bars when being used for high current load.All bus covers with heat-shrinkable T bush, and flat branch line is connected with fixed contact box main bus bar through the bolt wiring.Bus passes through switch cubicle dividing plate place and supports with insulating sleeve, if outlet internal fault electric arc in the cabinet can prevent that bus from running through fusing, the assurance accident is unlikely to spread to adjacent cabinet, and avoids main bus bar to be out of shape because of electrodynamic effect.
(3) can adorn the relaying protection element, instrument, the secondary device of charged supervision indicating device and specific (special) requirements in the control room 8.Control circuit is located in the wire casing in enough spaces, and metal cover board is arranged, and the left side wire casing is for the introduction of controlling little bus and draws reservation that the inner secondary line of switch cubicle self is located at the right side.Leave also on the side plate of control room that little bus passes through the position, hole so that construction.
(4) guide rail that supplies circuit breaker cart to slide has been installed in handcart chamber 9.Handcart can move between service position, test position, isolated location.Movable curtain plate is processed by metallic plate, is installed on the rear wall of handcart chamber.Handcart moves to the process of service position from isolated location, test position; The preceding movable curtain plate of fixed contact that is contained on the fixed contact box in bus cell and the cable vault is automatically opened; Move handcart in the other direction; Movable curtain plate auto-closing is closed the fixed contact box, thereby has ensured that operating personnel do not touch electrified body.Handcart is closed under the situation at the door of switch cubicle and is operated; Can see handcart residing position in cabinet through observation window, the while also can see On (with so that breaker closing)/OFF (with so that breaker open operation) button and the ON/OFF mechanical pointer on the handcart and energy storage/releasing can status indicator.
Medium Voltage Switchgear of the present invention also is provided with reliable interlock, and for operating personnel and attendant provide reliable safeguard protection, it acts on as follows:
(1) after handcart moved to isolated location, test position from the service position, movable curtain plate separated the fixed contact box, prevents the mistakenly entering into charged compartment.During maintenance, available padlock locks movable curtain plate.
When (2) circuit breaker is in "on" position, handcart can not pull out from the service position or from the isolated location, test position is pushed into the service position; The handcart of circuit breaker is lock test position or service position fully.
Could be operated when (3) earthed switch is only outside handcart is in isolated location, test position and cabinet, when earthed switch was in "on" position, handcart can not be from the isolated location, test position retreats to the service position.
(4) handcart is when the service position, and secondary plug is locked and can not unplugs.
Compress switch in the present invention and be equipped with pressure relief device in the cable vault 2, bus-bar room 3, handcart chamber 9 of cabinet.This pressure relief device is provided with handcart chamber pressure release cover plate 6 for the top that the top that is provided with cable vault's pressure release cover plate 4, bus-bar room at the top of cable vault is provided with bus-bar room pressure release cover plate 5, handcart chamber; On each pressure release cover plate, be equipped with a nylon rivet 7.In the high altitude localities, along with height above sea level increases, outside atmosphere air pressure reduces gradually, and when the air pressure in each compartment reached certain intensity, pressure can be washed nylon rivet 7 open and carry out pressure release, and the interior atmospheric pressure of each compartment and the atmospheric pressure of switch external are consistent.High height above sea level Medium Voltage Switchgear is that source improves design with common Medium Voltage Switchgear, and cabinet size and common Medium Voltage Switchgear are consistent, and supporting solid sealing type vacuum circuit breaker makes it not receive the adverse effect of extraneous factors such as condensation, filth as cut-offfing element.According to the relevant criterion requirement, the installation site of primary element is revised by the instructions for use of 4000 meters of height above sea level, strengthens the creepage distance of insulation distance, insulating part between conductor, and bus is all done fillet and handled, and avoids point discharge.
The present invention is according to specific factors such as high altitude localities meteorological conditions and development product, and the technical performance of components and parts all will satisfy the specification requirement of high height above sea level, thereby makes product reach the technical performance of high altitude localities.
