Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
First embodiment
The present apparatus includes threephase asynchronous 10, W1 ports, U2 ports and the V2 of the threephase asynchronous 10
Port is connected by the first wire 1 with adjustable current source 20, the U1 ports of the threephase asynchronous 10, V1 ports and
W1 ports are also connected by the second wire 2 with the adjustable current source 20, and the adjustable current source 20 adjusts dress provided with electric current
21 are put, the adjustable current source 20 is connected with external power supply.
Dehumanization method in the present embodiment is as follows, referring to the drawings shown in 1, comprises the following steps：
S1, the minimum line current value A for checking the threephase asynchronous that need to dehumidify；
S2, selection adjustable current source 20；
S3, the W2 ports, U2 ports and V2 ports of threephase asynchronous be serially connected with the first wire 1, will
U1 ports, V1 ports and the W1 ports of threephase asynchronous are serially connected with the second wire 2；
The first wire 1 and the second wire 2 in S4, the S3 steps are connected with the adjustable current source 20；
S5, the external power supply for connecting adjustable current threephase asynchronous source 20, the coil of threephase asynchronous is only
As heating resistor, the output current of the adjustable current source 20 is now adjusted, it is less than the threephase asynchronous
Minimum line current value A, then can ensure when to coil heats, and threephase asynchronous is in the state of safety, due to coil
The moisture for being attached to surrounding can be driven away by producing heat, reach that threephase asynchronous can be removed without being disassembled from facility
Wet purpose.
As the further improvement of this dehumanization method, the S5 steps are carried out by following sub-step：
A1, connection adjustable current source 20, regulation adjustable current source 20 current value is B, duration 30min, monitoring process
The middle coil temperature for requiring threephase asynchronous is no more than the temperature value that the name plate of motor is demarcated, if it exceeds nameplate temperature,
B values are then turned down, untill detection requirement is reached.
Increase safety of the purpose of this step for further protection threephase asynchronous, it is ensured that implementing the utility model
During the dehumanization method of offer, the performance of motor is unaffected.It can be point thermometer infrared monitoring to monitor coil temperature, can also be pacified
Fill temperature sensor and carry out computer monitoring.
A2, the electricity for keeping cutting off the adjustable current source 20 in a1 after the current value B 1-2 hours of adjustable current source 20
Source is supplied, and the coil temperature to threephase asynchronous recovers to room temperature state, then the coil of threephase asynchronous is entered
Row insulation resistance value is detected, is such as met insulating requirements, is then completed the dehumidifying of threephase asynchronous, insulating requirements are not met such as,
This step is then repeated untill the coil insulation resistance of threephase asynchronous conforms to evaluation.
The monitoring of insulation resistance value recommends pincerlike card flow table, generally, when pincerlike card flow table test value reaches 200
I.e. it is believed that dehumidifying terminates more than megaohm.
Specifically, the current value B of adjustable current source 20 in a2 steps retention time is 1.5 hours.
Specifically, the B values are the minimum line current value A of threephase asynchronous 1/2-3/4,2/3 beginning preferably is selected from
Tested.
Specifically, the adjustable current source 20 is adjustable DC current source.
