Description
Technical Field
The invention relates to the field of motor fault detection, in particular to a fault pump stopping alarm device for an automatic water pump.
Background
At present, automatic water draining pumps of transformer substations are often easy to stop pumps for various reasons, and common reasons include idle tripping, overload action, water pump failure and various loop disconnection. At present, a mode of voltage detection and flow switch is mainly adopted to judge whether the water pump normally operates.
However, the voltage detection mode cannot detect and distinguish the shutdown caused by the failure of the water pump; the mode of adopting the flow switch has the defects of troublesome installation and unsuitable installation on some sites. Because the water pump can not be distinguished whether the water pump is stopped due to failure or no ponding condition, the water pump failure can not be correctly alarmed, so that an operator can not know the running state of the water pump, and the risk of ponding exists in the power equipment.
Disclosure of Invention
The invention provides a fault pump stop detection and alarm device for an automatic water pump, which aims to solve the technical defect that the existing fault pump stop detection device for the water pump cannot accurately distinguish whether the water pump stops due to fault.
The technical means adopted for realizing the aim of the invention are as follows:
a fault pump stopping detection and alarm device for an automatic water pump comprises a direct-current power supply, a liquid level switch F1, a relay, an alternating current detection module L1, a breaker QF, an alarm indication module and a water pump M;

the power supply L end of the water pump M is connected to the mains supply through a breaker QF and normally open contacts J1-3 of the relay, the power supply N end of the water pump M is connected to the mains supply through the breaker QF, and either the power supply L end or the power supply N end of the water pump M passes through a central hole of the through type current transformer in the alternating current detection module L1. The current of the water pump M is sampled and input through a through type current transformer in the alternating current detection module L1, and when the collected current is smaller than a set value of the current detection module L1, a normally open contact L1-1 is closed.
In the scheme, the water level of the cable well is detected through the liquid level switch and acts on the relay, and the operation condition of the water pump is detected by the cooperation of the alternating current detection module, so that the water pump is started to alarm when the water pump stops due to the fault due to the water drainage of the cable well, the correct alarm of the water pump due to the fault is realized, and meanwhile, the automatic water pump fault stop detection and alarm device is simple to install and high in practicability.

Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the present patent;
for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions;
it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1 and 2, the automatic water pump fault pump stop detection and alarm device comprises a 12V direct-current power supply, a liquid level switch F1, a relay, an alternating current detection module L1, a buzzing alarm indicator lamp HD1 and a water pump M;
one end of a normally open contact F1-1 of the liquid level switch F1 is connected with the positive electrode of the direct current power supply, and the other end of the normally open contact F1-1 is connected with the negative electrode of the direct current power supply through a coil J1 of a relay;
one end of a normally open contact J1-1 of the relay is connected with the positive electrode of the direct current power supply, and the other end of the normally open contact J1-1 is connected with the negative electrode of the direct current power supply through an input contact of a power supply in an alternating current detection module L1;
one end of a normally open contact J1-2 of the relay is connected with the positive electrode of the direct current power supply, and the other end of the normally open contact J1-2 is sequentially connected with the negative electrode of the direct current power supply through a normally open contact L1-1 and a buzzer alarm indicator lamp HD1 which are output by an alternating current detection module L1;
the power supply L end of the water pump M is connected to the mains supply through a breaker QF and normally open contacts J1-3 of the relay, the power supply N end of the water pump M is connected to the mains supply through the breaker QF, and either the power supply L end or the power supply N end of the water pump M passes through a central hole of the through type current transformer in the alternating current detection module L1. In this embodiment, the power supply N end of the water pump M passes through the central hole of the through-type current transformer in the ac current detection module L1.
The liquid level switch F1 used in the embodiment is a floating ball liquid level switch which is arranged on the side wall of the cable well in a suspending way, when the water level of the cable well rises to the upper water level, the floating ball head is upward, and a normally open contact F1-1 output by the floating ball liquid level switch F is closed; when the water pump M acts to drain water to enable the water level to drop, the floating ball head is sunk to the lower water level, and the normally open dry contact F1-1 output by the floating ball liquid level switch F1 is disconnected. I.e. when draining, the upper water level is closed and the lower water level is opened.
The alternating current detection module L1 has a lower limit action function and a current detection module action delay function, and adopts an external through type current transformer to collect current. That is, when the current value collected by the current transformer is smaller than the lower limit value set by the ac current detection module L1 and exceeds the delay time of the preset ac current detection module after the ac current detection module is powered on, the ac current detection module L1 meets the action condition, and the normally open contact L1-1 output by the ac current detection module L1 is closed. The action delay function of the alternating current detection module L1 can avoid false alarm caused by short closing of the normally open contact L1-1 output by the alternating current detection module L1 due to certain delay of the action of the water pump M compared with the action of the alternating current detection module L1.
Example 2
When the water level of the cable well rises to the upper water level and the water pump M stops pumping due to faults, the working condition of the detection and alarm device is detected: when the water level of the cable well rises to the upper water level, the micro switch in the floating ball liquid level switch F1 acts, the output normally open dry contact F1-1 is closed, the coil J1 of the relay is electrified, the output normally open contacts J1-1, J1-2 and J1-3 are closed, and the power supply input of the alternating current detection module L1 is connected after the J1-1 is closed, namely the alternating current detection module L1 starts to work at the moment. When the alternating current detection module L1 collects that the current of the main circuit of the water pump M is smaller than a preset lower limit action value, the water pump M is considered to be stopped, a normally open contact L1-1 output by the alternating current detection module L1 is closed, and the buzzer alarm indicator lamp HD1 sends an alarm signal.
Because the other end of the normally open contact J1-1 output by the relay is connected with the negative electrode of the direct current power supply through the power supply of the alternating current detection module L1, namely the power supply of the alternating current detection module L1 is blocked by the normally open contact J1-1 of the relay, when the water level does not reach the upper water level where the water pump M is required to operate, the alternating current detection module L1 does not work, and therefore the buzzer alarm indicator lamp HD1 cannot conduct to work.
Example 3
When the water level of the cable well rises to the upper water level and the water pump operates normally, the working condition of the detection and alarm device of the embodiment is approximately the same as that of the embodiment 1, except that when the alternating current detection module L1 collects that the current of the main circuit of the water pump M is greater than the preset lower limit action value, the water pump M is considered to operate normally, so that the normally open contact L1-1 output by the alternating current detection module L1 is disconnected, and the buzzing alarm indicator lamp HD1 cannot be conducted to operate.
The terms describing the positional relationship in the drawings are merely illustrative, and are not to be construed as limiting the present patent;
it is to be understood that the above examples of the present invention are provided by way of illustration only and not by way of limitation of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
