Description

Short-circuit-proof voltage acquisition integrated device for storage battery
Technical Field
The utility model relates to a battery on-line monitoring technique, concretely relates to short-circuit voltage collection integrated device is prevented to battery.
Background
The storage battery is widely applied to various industrial fields as energy storage equipment, the storage battery online monitoring system has great significance for safe and reliable use of the storage battery, but the storage battery online monitoring system also brings the risk of short circuit to the storage battery while sampling the voltage of the storage battery, and the short circuit of the storage battery can generate serious consequences such as fire, explosion and the like.
The short-circuit protection of the sampling loop of the existing storage battery online monitoring system generally adopts a mode of adding insurance or resistance in a sampling circuit, so that the protection range is limited, and the use times are limited; and the protective device added on the sampling line has a complex structure, is easy to fall off and is not easy to protect. Therefore, the existing measures lack a solution with simple structure, high integration, wide protection range and convenient use and maintenance.
SUMMERY OF THE UTILITY MODEL
For overcoming current battery on-line monitoring device to the technical defect of battery short-circuit protection, the utility model provides a simple structure, convenient operation, protection are more effectual prevent short-circuit voltage collection integrated device.
The utility model provides a technical scheme that above-mentioned technical problem adopted is:
the short-circuit voltage collection integrated device is prevented to battery includes: the PTC thermistor is connected with the opening sampling terminal and the voltage sampling line and packaged in the opening sampling terminal.
As a further optimization, the PTC thermistor is provided with two welding pins, and the two welding pins of the PTC thermistor are respectively connected with the opening sampling terminal and the voltage sampling line in a welding mode.
As further optimization, the PTC thermistor is packaged on the opening sampling terminal through pouring sealant.
The utility model has the advantages that:
the PTC thermistor is welded with the opening sampling terminal and the voltage sampling line and integrally installed, when a sampling loop is short-circuited, the resistance value of the thermistor rises, so that current is limited, the whole sampling loop is effectively protected, the voltage protection range provided by the PTC thermistor is DC250V, and effective protection can be provided for short circuit among a plurality of series-connected storage batteries. The thermistor recovers automatically after short circuit is eliminated, multiple protection can be carried out, the protection is more reasonable, and the use is more convenient.

Fig. 1 is a schematic front view of an integrated device according to an embodiment of the present invention;
fig. 2 is a schematic side view of an integrated device according to an embodiment of the present invention;
labeled as: 1-opening sampling terminal, 2-PTC thermistor, 3-sampling line and 4-pouring sealant.
Detailed Description
The utility model aims at providing a simple structure, convenient operation, protection are more effectual prevent short circuit voltage and gather integrated device. The device includes opening sampling terminal, PTC thermistor, voltage sampling line, PTC thermistor welded connection opening sampling terminal and voltage sampling line to encapsulate in opening sampling terminal, realize integrated integration, thereby PTC thermistor rises along with the electric current increases the temperature when the sampling return circuit short circuit and increases resistance value restriction short-circuit current and provide the protection to battery and interface circuit, and the device structure that has now is simpler, and protection range is wide in range, and it is more convenient to use.
Example (b):
as shown in fig. 1 and fig. 2, the storage battery short-circuit prevention voltage acquisition integrated device in the embodiment includes: the PTC thermistor comprises an opening sampling terminal 1, a PTC thermistor 2 and a voltage sampling line 3, wherein the PTC thermistor 2 is provided with two welding pins which are respectively connected with the opening sampling terminal 1 and the voltage sampling line 2 in a welding mode, and then the opening sampling terminal 1 and the voltage sampling line 2 are packaged and integrated into a whole by pouring sealant 4.
When the sampling circuit is short-circuited, the PTC thermistor 2 increases the temperature along with the increase of current so as to increase the resistance value to limit the short-circuit current and provide short-circuit protection. The utility model discloses a simple structure, convenient operation improves short-circuit protection's validity greatly, has fine practicality and application prospect.
