Abstract
本实用新型公开了一种电动机保险自动切换装置，包括熔断保险一和熔断保险二，所述熔断保险一和熔断保险二并联在电动机的电源侧，所述熔断保险一与智能断路器一连接，所述熔断保险二与智能断路器二连接，所述电动机的电源线路设置启动控制按钮和停止控制按钮。熔断保险一按电动机的启动电流大小配备，熔断保险二按电动机的工作电流大小配备，操作时按下启动控制按钮随即智能断路器一合上，在6秒后智能断路器一自动断开，同时智能断路器一合上后5秒智能断路器二合上。当停用电动机时按停止控制按钮即可。智能断路器一和熔断保险一可保证电动机正常启动，电动机工作时自动切换到智能断路器二和熔断保险二工作。在遇到故障时熔断保险二迅速断开。
The utility model discloses an automatic switchover device for electric motor insurance, which comprises a fuse fuse 1 and a fuse fuse 2, the fuse fuse 1 and fuse fuse 2 are connected in parallel on the power supply side of the motor, the fuse fuse 1 is connected with an intelligent circuit breaker 1, The fuse 2 is connected to the intelligent circuit breaker 2, and the power line of the motor is provided with a start control button and a stop control button. Fuse fuse 1 is equipped according to the starting current of the motor, and fuse fuse 2 is equipped according to the working current of the motor. When operating, press the start control button and then the intelligent circuit breaker will be closed. After 6 seconds, the intelligent circuit breaker will automatically disconnect. At the same time Smart circuit breaker 1 is turned on 5 seconds after smart circuit breaker 2 is turned on. Press the stop control button when deactivating the motor. The first intelligent circuit breaker and the first fuse can ensure the normal start of the motor, and automatically switch to the second intelligent circuit breaker and the second fuse when the motor is working. Fuse fuse two is disconnected rapidly when running into a fault.
Description
Technical field
The utility model belongs to the motor technology field, is specifically related to a kind of motor insurance automatic switching control equipment.
Background technology
Motor burns out studies carefully its main cause; Being that to open the fuse model that the power supply knife switch of motor uses too big, is because because the starting current of single-phase motor is 2～3 times of its rated current, the starting current of threephase motor is 5～7 times of its rated current; As adopt a knife switch to control; The fuse of selecting for use must escape starting current, but when operate as normal, the fuse of being selected for use just seems that model is too big; Do not have due protective effect, can not cut off the electricity supply when causing motor that fault is arranged causes that motor burns out.If adopt other safeguard measure expenses to increase greatly, still do not have cost-effective measure at present.
The utility model content
The purpose of the utility model is to avoid above-mentioned weak point of the prior art, and a kind of effective protection motor is provided, effectively prevents that motor from burning out, motor esy to use, safe and reliable, easy and simple to handle insurance automatic switching control equipment.
The technical scheme that purpose adopted that realizes the utility model is: a kind of motor insurance automatic switching control equipment; Comprise fusing insurance one and fusing insurance two; Said fusing insurance one and fusing insurance two are connected in parallel on the mains side of motor; Said fusing insurance one is connected with intelligent breaker one, and said fusing is insured two and is connected with intelligent breaker two, and the power circuit of said motor is provided with the start-up control button and stops control button.
Because the utility model is in 2 two fusing insurances of fusing insurance one in parallel of the mains side of motor and fusing insurance; The starting current size that motor is pressed in fusing insurance one is equipped with; The operating current size outfit of motor is pressed in fusing insurance two, before fusing insurance one and fusing insure two, respectively is equipped with intelligent breaker one and intelligent breaker two.The start-up control button is set and stops control button at the power circuit of motor, press during operation the start-up control button immediately intelligent breaker one close intelligent breaker one automatic disconnection after 6 seconds; Meanwhile intelligent breaker one back 5 seconds (motor the is operate as normal) intelligent breakers two that close close.When stopping using motor, get final product by stopping control button disconnection intelligent breaker two.During motor start-up, intelligent breaker one can guarantee that with fusing insurance one work motor normally starts like this, when electric motor normal working, automatically switches to intelligent breaker two and fusing insurance two work.Fusing insurance two is broken off rapidly under the situation that runs into faults such as electric current is excessive, phase shortage, just can play due protective effect to motor, and can not cut off the electricity supply in the time of can fault not being arranged because of motor causes that motor burns out.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the circuit diagram of the utility model.
Embodiment
As shown in Figure 1: a kind of motor insurance automatic switching control equipment; Comprise fusing insurance 1 and fusing insurance 22; Said fusing is insured 1 and is connected in parallel on the mains side of motor 3 with fusing insurance 22; Said fusing is insured 1 and is connected with intelligent breaker 1, and said fusing is insured 22 and is connected with intelligent breaker 25, and the power circuit of said motor 3 is provided with start-up control button 6 and stops control button 7.
Utilize the utility model; 22 two fusing insurances of mains side parallel connection fusing insurance 1 and fusing insurance at motor 3; The starting current size that motor is pressed in fusing insurance 1 is equipped with; The operating current size outfit of motor is pressed in fusing insurance 22, before fusing insurance 1 and fusing insure 22, respectively is equipped with intelligent breaker 1 and intelligent breaker 25.Start-up control button 6 is set and stops control button 7 at the power circuit of motor 3, press during operation start-up control button 6 immediately intelligent breaker 1 close intelligent breaker one 4 automatic disconnections after 6 seconds; Meanwhile intelligent breaker 1 back 5 seconds (motor the is operate as normal) intelligent breakers 25 that close close.When stopping using motor, get final product by stopping control button 7 disconnection intelligent breakers 25.During motor start-up, intelligent breaker 1 can guarantee that with fusing insurance one 1 work motor normally starts like this, when electric motor normal working, automatically switches to intelligent breaker 25 and fusing insurance 22 work.Fusing insurance 22 is broken off rapidly under the situation that runs into faults such as electric current is excessive, phase shortage, just can play due protective effect to motor, and can not cut off the electricity supply in the time of can fault not being arranged because of motor causes that motor burns out.
