Description
Technical field
This utility model is related to electric motors, and more particularly, to a kind of 6kV motor outlet box installs electric heater additional
Attachment structure.
Background technology
At present, domestic 6kV high-tension motor only installs electric heater additional in motor body interior, during ensureing that motor does not run
Dielectric level, but the insulation after high humility heavily contaminated region is not enough to ensure that motor is long-time and stops transport is in acceptability limit.
Hong Shan steam power plant of Fujian Province is the auspicious sesame in Quanzhou Shishi City, great mountain, the printing and dyeing enterprise in still coastal three towns of brocade provide industrial heat, mainly
Climatic characteristic is：Heat enriches, rainfall is concentrated, and major casualty is typhoon, heavy rain, storm tide etc..Find all when unit puts into operation
6kV high-voltage motor all cannot keep, when stopping transport, qualified, the particularly electricity such as air-introduced machine, primary air fan, pressure fan that insulate for a long time
Machine, under 2-5 month rainy wet weather, stoppage in transit 1-2 hour insulating requirements drop down to, under acceptance line, badly influence equipment
Power transmission puts into operation and unit starting is in some instances it may even be possible to the equipment short circuit of causing such as burns at the severe economic and social impacts on time.
Patent No. 201520602805.3, a kind of entitled fire-proof motor assistant junction box, including being fixed on motor
Junction box seat on support line outlet and connector cover composition rosette, junction box seat is provided with incoming line assembly parts and
Line outlet assembly parts；In the inside of described junction box seat, patch panel is installed, connecting stator thermometric lead is distinguished on patch panel, adds
Hot device lead and measuring temperature of bearing lead, described stator thermometric lead, heater lead are via the rubber being arranged on junction box seat bottom
Plug carries out glue and is sealed closing after introducing rosette, and described measuring temperature of bearing lead passes through inlet wire along the electric machine stand surface left and right sides
Mouth assembly parts introduce in rosette, between external stator thermometric lead, heater lead and measuring temperature of bearing lead and junction box seat
It is attached sealing through line outlet assembly parts；This technical scheme is not enough to keep motor under 2-5 month rainy wet weather
Stoppage in transit 1-2 hour insulating requirements are it is impossible to meet the insulating requirements of 6kV motor outlet box.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides that a kind of structure is simple, behaviour
Make attachment structure convenient, that practical 6kV motor outlet box installs electric heater additional.
This utility model is realized in the following way：
A kind of 6kV motor outlet box install additional electric heater attachment structure it is characterised in that：Including primary heater 1,
Secondary heater 2,6kV motor outlet box 3, power switch cabinet 4, described primary heater 1 power cathode end and the second heating
Device 2 power cathode end is connected by wire 5；It is provided with terminal block 6 in described 6kV motor outlet box 3；Described primary heater
1 power positive end is connected with the power positive end of power switch cabinet 4 by terminal block 6；Described primary heater 1 and second adds
Power cathode end after wire 5 connection for the hot device 2 is connected with the power cathode end of power switch cabinet 4 by terminal block 6.
It is provided with ammeter 7 in described power switch cabinet 4.
The beneficial effects of the utility model are：Structure is simple, low cost, easy to operate, effectively increases motor
Insulating reliability, compensate for existing heater and is not enough to keep the defect of electrical machine insulation, have significant economic benefit and important
Security implications.
Brief description
Fig. 1 this utility model structural representation.
Specific embodiment
In conjunction with accompanying drawing in detail, this utility model specific embodiment is described in detail：
As shown in figure 1, a kind of 6kV motor outlet box installs the attachment structure of electric heater additional, including primary heater 1,
Secondary heater 2,6kV motor outlet box 3, power switch cabinet 4, primary heater 1 power cathode end and secondary heater 2 electricity
Source negative pole end is connected by wire 5；It is provided with terminal block 6 in 6kV motor outlet box 3；Primary heater 1 power positive end leads to
The power positive end crossing terminal block 6 with power switch cabinet 4 is connected；Primary heater 1 and secondary heater 2 pass through wire 5 even
Power cathode end after connecing is connected with the power cathode end of power switch cabinet 4 by terminal block 6.
Be provided with ammeter 7 summation current transformer in this utility model power switch cabinet 4, in order to observe primary heater 1,
Two heater 2 electric current is it is ensured that primary heater 1, secondary heater 2 effectively put into.
This utility model primary heater 1, secondary heater 2 adopt baffle heater, are about 15cm, wide about 5cm, thickness
Less than 1cm, rated voltage 220V or 380V, power is pressed 6kV motor outlet box 3 space size and is selected 50-100W；The
One heater 1, secondary heater 2 can be separately mounted to 6kV motor outlet box 3 both sides centre position, electronic also dependent on 6kV
Machine outlet box 3 inner cable outlet position, selects to install near the position of cable it is ensured that heat can be concentrated is baked to cable and absolutely
Edge.
In the present embodiment, before electrical operation, primary heater 1, the disconnection of secondary heater 2 power supply are exited first and added
Hot device 1, secondary heater 2 run, and put into primary heater 1, secondary heater 2 power supply after motor is out of service, the
Can check whether electric current is specified, such as by the ammeter 7 in power switch cabinet 4 when one heater 1, secondary heater 2 run
Carry out maintenance replacing primary heater 1, secondary heater 2 less than specified；Primary heater 1, the cable of secondary heater 2 are led
Line process must wear flexible metal conduit, prevents exposed, 6kV motor outlet box 3 hole stifled mud and glass cement closure.
