Description

Heat protector of motor timing test device

Technical field

The utility model is related to a kind of test devices, more particularly, to a kind of motor heat being used on heat protector of motor Protector timing test device.

Background technology

Motor refers to a kind of calutron realized electric energy conversion according to the law of electromagnetic induction or transmitted, and main function is Driving torque is generated, as electric appliance or the power source of various machineries.And motor is in the process of running, if there is clamping stagnation situation, Although the power output shaft of its motor stops rotating, but its internal component, still in implementation, energy can not be released, lead The electric current sent a telegraph inside machine is excessive, and temperature is excessively high, gently then reduces the service life of motor internal component, heavy then make inside motor Component is burnt out, and causes motor that can not use.Although there are also current of electric is excessive and the excessively high cut-off motor power of temperature Heat protector of motor, however only be realize heat protective effect, without to heat protector of motor carry out protection timing effect, no Reaction motor can preferably be embodied and carry out Thermal protection duration, thermal protection for motors cannot be more preferably obtained and carry out state, be unfavorable for carrying out The more preferable product that obtains further is researched and developed and safeguards reference information data.

Utility model content

The utility model is to solve existing heat protector of motor cannot preferably embody reaction motor progress Thermal protection duration, Thermal protection for motors cannot more preferably be obtained and carry out state, be unfavorable for more preferably obtain the further research and development of product and safeguard reference information The present situations such as data and provide it is a kind of can preferably embody reaction motor carry out Thermal protection duration, can more preferably obtain thermal protection for motors Carry out state more conducively carries out the more preferable heat protector of motor timing for obtaining product and further researching and developing and safeguarding reference information data Test device.

Used specific technical solution is the utility model to solve above-mentioned technical problem：A kind of thermal protector timing survey Trial assembly is set, including heat protector of motor, it is characterised in that：Further include Hall current sensor interface, relay, operation timing Device, reset timer, reset button and test indication panel, set Hall current sensor interface and relay in thermal protector, Thermal protection for motors line is electrically connected after running through Hall current sensor with thermal protector, the control monolithic of relay and thermal protector Machine is mutually electrically connected, and running timer and bit timer are electrically connected with relay respectively, reset button respectively with running timer and Reset timer is electrically connected, and Hall current sensor is mutually electrically connected by Hall current sensor interface with control single chip computer；It surveys Resetting time display, run time display, run indicator and homing light are set on examination indication panel, resetting time is aobvious Show that device is mutually electrically connected with reset timer, run time display is mutually electrically connected with running timer, homing light and reset button It is mutually electrically connected, run indicator is mutually electrically connected with running timer.Validity test records the information such as Thermal protection run time, can be preferably It embodies reaction motor and carries out Thermal protection duration, can more preferably obtain thermal protection for motors and carry out state, more conducively carry out more preferably being produced Product are further researched and developed and safeguard reference information data

Preferably, set clearing reset button on the test indication panel, reset reset button respectively with resetting when Between display, run time display be mutually electrically connected.It improves to reset and resets convenient validity.

Preferably, setting 24V switch DC power supplys in the thermal protector.Stable chip operation power supply is provided.

The utility model has the beneficial effects that：Validity test records the information such as Thermal protection run time, can preferably embody React motor and carry out Thermal protection duration, can more preferably obtain thermal protection for motors and carry out state, more conducively carry out it is more preferable obtain product into One step is researched and developed and safeguards reference information data.

Description of the drawings：

The utility model is described in further detail with reference to the accompanying drawings and detailed description.
